/sci/ - Science & Math

My schedule:

> Wake up
> Work out
> Make breakfast
> Sit at computer trying to focus on big thing I'm supposed to do /learn
> Remember there is some smaller, more immediate thing I'm supposed to do
> Start doing smaller thing
> Lunch
> Finish doing smaller thing
> Dinner
> Try to focus on bigger thing
> Am too tired to focus on it, try to read relevant physics material that will get me excited to work on it instead
> Go to sleep
> Don't retain what I read or did that day

How the heck am I supposed to ever get anything done?

I've tried prepping food faster/ working out faster, and I can't eat out or not work out because I will just feel like garbage and not even finish the small things.

Honestly, I don't understand it. Anyone who can help me get some intuition?
