And I guess a way of how to do that. Once I started thinking about how much my thoughts affect what I do, and how much media influences your thoughts I kinda found the whole act of consuming disgusting. A machine you stare into while you wait to die in a sense that affects your thinking.
And after you consume minimally you have time to do a lot, just do nothing until you're so bored you want to do math and once you start you'll see into the beauty of a conceptual world and a different frame of mind.
Start from the beginning, precalculus and discrete math 1 material.

Not sure, just try every day. Train every type of thinking.
I don't know about any certain book, I've read quite a lot and reading works similar to a recursive function for me.
The most important thing I find is to really be honest with yourself on a deep level without ego of what you know, while simultaneously telling only yourself that you are smart and can solve any problem when you're put in a position where you need to solve it. This way you'd know if you really understand and comprehend something, and if you don't you need to shut down your ego and quickly go through high school level material again for whatever material you're trying to understand and solve.
For me this strategy creates this certain intuitive system for me where you know what you don't know but tell yourself that you can with practise and that you should do it.
And I follow the rule that I don't understand something properly until I can visualize the system or process of it occurring abstractly.
I also stopped existing solely in my own mind, splitting my consciousness between mind, body, consumed information and environment. Makes you look at what you're really doing in a better and healthier way.
Suddenly the world stopped being this lost disgusting place and instead became a beautiful space of reason and patterns to explore. You look at everything differently, snow stops being cold and irritating in your mind but instead becomes complex and beautiful following given underlying rules.

I live alone and basically my entire waking hour alternates between me studying for uni and playing the one video game I still enjoy. I'm worried that I will slowly end up in a position where I'll just like learning for the sake of learning and not have an overall goal. This isn't exactly a bad thing but I have a friend living almost the exact same lifestyle as me but he's diagnosed with clinical depression and lockdown restrictions really don't help.

Imo I've never had a more relaxing and enjoyable lifestyle in the past 9~ months, limiting your interactions with all the horseshit consumerist aspects of media is liberating but doing this without negating positive social interaction has been quite tough. Obviously buying shit you don't need will never bring long-term happiness but it's still easier to live this lifestyle and I think you have to experience some hedonism before you can fully make up your mind. Accumulating material wealth will always be easier than spiritual wealth, it's a shitty platitude but it's true and it's probably why many billionaires end up doing philanthropic work when they're finished pillaging the world (assuming they're not just building their legacy).

I stopped doing anything but reading books & browsing /sci/ & /biz/ when I was 17 due to the ultimate blackpill that behavioural psychology is, so I had assumed that you were the same. however, these two posts proved that we are very different, and I wonder how have you achieved this level. after the aforementioned blackpill, I just became somewhat depressed. The only thing that has kept me going for the past year (I'm now 18) is the dream of becoming a quant. I don't even feel anything anymore, just doing what is required for this goal, and hoping that one day something will change in my life.
Now that you have my background, would you please provide me with any advice regarding this? For example, I don't understand what you mean by
> I also stopped existing solely in my own mind, splitting my consciousness between mind, body, consumed information and environment. Makes you look at what you're really doing in a better and healthier way.

I have tried to minimize the inner dialogue (since it's slow), and relearn visualising stuff for entertainment (when I was 13-15, I would close my eyes and sometimes a green circle appeared, which I would then watch as it expands and does other weird things).
Is that what you mean?

So I hear a lot of people saying that they're nervous about mRNA vaccines because they're new. Moreover, people rather frequently claim that one year is not enough to demonstrate safety of the technique of mRNA vaccination. However, some of these concerns are based on incomplete knowledge of the history of mRNA vaccination. While these types of vaccines are relatively novel, they are not nearly as novel as people tend to think.

The first demonstration of an expression response following mRNA injection dates back to 1990 [1], and a numerous clinical trials have been done since that time. Some examples can be found here: [2-4]. These studies include monitoring participants for adverse events for extended periods of time, far longer than the claims I often see here. See [5] for a good overview of safety assessments of vaccination using mRNA platforms.

Aside from that, people often forget that the field of mRNA therapeutics as a whole is even older [6; pic related]. This field has been concerned with any potential adverse events that it could produce. Nevertheless, the predominant reason for why mRNA based therapeutics haven't yet taken off full scale aren't safety concerns, but methodological issues stemming from the instability of mRNA in vivo. It tends to be broken down quickly, and requires some degree of stabilization for it to be able to reach its therapeutic potential. With recent advances, these obstacles have now been overcome. The point here is that the intrinsic instability of mRNA is something that strongly acts *against* the potential for long-term adverse effects.

So we know that the technique is safe, and now that we know it works, it's time to start rolling it out.

Two shots actually, not three.

How long immunity lasts is somewhat of an open question, but some initial inference can be made: after infection with the virus itself, antibody levels drop down after a while, but T-cell immunity appears to remain steady, at least for the 8 month longitudinal studies that have been conducted thus far. This means that after some time (months) you'll likely lose sterilizing immunity (i.e. you cannot get sick), but you'll retain base immunity (meaning that if you're re-infected, you won't get very sick). Whether you'd need a follow up shot depends on your risk group: probably not necessary for some years if you're young and healthy.

>mrna vaxs even more developed, especially since they may be applied to cancer treatments
Me too. mRNA therapeutics in general are astoundingly promising, and could potentially also be applied to neurodegenerative and auto-immune disease like Huntingtons and MS. That's the upside of this pandemic: it poured a shit ton of resources into getting this stuff off the ground.

No, stronger selection in men leads to a healthier population full stop. One of the explanations for gender existing *at all* is that it allows for half the population to bear heavy selective pressure while preserving parental investment in children.

Consider a situation where all humans are selected strongly, regardless of gender. A tenth of people have some ten children, and everybody else gets no kids. Sure, we'll have a strong gene pool, but there's less investment in child rearing because every parent is balancing their 20 kids.

Alternatively, you could have weak selection across all people regardless of gender. Everybody only replaces themselves, fully investing in child reading but relaxing selective maintenance of the gene pool.

Gender (female mate choice in particular) gives you both. Women have between 1 and three children while only the most fit / desirable men have 3-6 (or more) kids.
