It takes a lifetime to build a better stronger version of yourself. If you can calm down & sit down for a while doing nothing towards something you desire, a weird laziness will somehow try to takeover your head space. We humans either lose patience or passion at a rapid speed. That maybe the biggest setback you are yet to experience. Be afraid & stay away from that.
Not some motivation for body, money or success, talking about how to be disciplined & pack some morals inside.
