This is the exact type of guy who is destined to fail. The problem is never your age but attitude as everyone who still operates under "i still have time" is destined to fail. Its blanked for under achievers, who think one day they'll become the guy they want to be, but forget that they are already living life.
If you want to draw, just start it. If you are reading this and you are in your late 20's or 30's here is the best advice I can give:
I'm not gonna bullshit you, your primetime is over, and yes teenagers and early 20's have it easier to memorize things, as its only a downhill from 30's. There are a lot zooms now, who pick up artsy fartsy careers, because they fucking hate working. (This is also why there is a huge tradesmen shortage). I also noticed my learning skill is still there, but definitely not as effective as it was many years ago. If it was 100% now its around 85%-ish.
You'll probably encounter a medical condition around this time too, for blue collars like me, lower back pain is like a default status. There is never going to be a perfect opportunity, like you'll only draw when you are happy and its a sunny perfect day, or you slept the perfect amount of hours. No, you'll need to draw when you are depressed at 2AM too. If you cannot function in misery, its over for you, not in drawing but in life itself.
If you actually want to improve you need to become OBSESSED. The I want to draw needs to be I need to draw.
