Reading Sartre

"Man is nothing else but what he makes of himself."

This is what Sartre said.
I read his reading recently and very impressed by the idea of
a man makes his own future and is responsible for his choices.
It seems pretty simple but I think I've forgotten this.

After I read it, I finally could see there are countless ways that I can choose.
I was always worried about which field I should work in or which field I have talents in. However, I finally found out that I don’t have to follow the way I seem to be good at or more like to success in.
Even if there’s a way that I think I cannot be so successful, if I choose to take it, the way becomes my way. No one force me to follow the easiest way and there is no way that I should follow.

I suddenly could feel very energetic and hopeful thinking that I can be anything that I want to be.
