There is just one thing that you can do to actually make you really fail in life: do nothing. And this nothing is nothing, nothing indeed. Because trying and not being able to accomplish success is not doing nothing. You are doing something, maybe the wrong one, but you are. Therefore you are not failing in life.

Doing nothing is to be stuck with no idea of where to go, what to choose and because of that you just stand still. Doing nothing is to watch life passing you by. Doing nothing is to function in an automatic pilot mode. Doing nothing is to let others write your life script.
So if you don’t want to fail in life do something. Even if it feels a tiny little invisible step. Just do it. And keep on going. Just don’t do nothing.
