Is 3 hours of study a day too much?

I am on disability and I am bored af everyday. I used to draw daily but then my health got worse. I’ve been doing better lately but find myself doomscrolling. I am eager to learn new things, I don’t care how bad I am because I find learning about art and technique fun. I plan to study from books and youtube but mostly draw for fun too. I do notice my anatomy and perspective are not good at all though and want to study it for 2-3 hours a day at least so I can be productive and not bored doomscrolling anymore (I made a study plan too).

I hear a lot of people get don’t like long hours of study so I am wary though and want to know if people here may have other recommendations on whether to do more or less? Thanks again.
