Seriously, why would anyone "break" themselves? I thought we were just learning from our mistakes...
I am very productive these days. I think when you truly love what you do, being an entrepreneur is just something you can tell people so they understand _why_ you don't work for someone.
I've worked at 9 - 6 before. I will never go back. Mostly because of the reward for not breaking myself and forgetting about what I love.
I mean how many people just like the joy of creating something for themselves and no one else. I do.
