Just staying alive would be fine. I believe that living on is equal to being a better person. Working on rationality might help me with doing so.

Hello, I am Kyo. I am new here, and I hope to become a better person. Thank you.
My personal experience: exercising makes me feel better. One can’t do much when he feels bad, right? Hence I believe that exercising makes one more productive. It helps me to cope with depression, too. I might feel very terrible sometimes, and in such moments exercising is what helps me to get back on track. Without exercising one will rot, I think. Exercising is good, in moderate measures.
It heavily depends on how hard one’s work is and how much time one has. From my personal experience:
1. I used to learn English around 5-8 hours everyday by reading native books that I did not understand.
2. I studied Japanese during three days for 10 hours each day, which resulted in 300 kanji learned in total.
Taking that into account, my personal opinion is that four hours/day is not a border, and one needs to explore his limits on his own.
Where do I start on this conquest?
