Life is all luck
I heard some "successful" actor say that he was just lucky and attributes all his success to luck. He said that he was lucky to have an interest in acting and was lucky to have followed that path.
I thought about this and it seems that yes everything is luck. If someone has enough willpower to pursue "success" every day and night, he/she is lucky to have that kind of willpower - many don't have that. Someone can be even more lucky by having a genuine interest in something so it never feels like work.
I don't have much willpower, but I'm lucky to have such a personality that gets inspired a lot. I just try to get inspired by something I have to do, so i don't need willpower. It's just luck to have that.
