I want to spend 10+ hours a day on improving myself
That's a lot. Do you think that is enough time to work on yourself?
10+ hours for me is more than enough
While it may seem like a long time, it is okay to work on yourself. You can improve yourself and make yourself happy.
I see no problem here.
Yeah, there really isn't as long as you have the free time! People really need to take care of themselves these days, life shouldn't only be about working all day. Your body and mind should be thanking you years down the line!
