How Do We Define Success?

I think my favorite quotes is Winston Churchill. Success is moving from failure to failure without loss of enthusiasm. And we should be really mindful that it often comes down to how do we define success. There are certainly plenty of people who release a book purely for the purpose of having it hit the top of the bestseller list. If it didn't do that, it's not a success. But that's their definition. It doesn't have to be mine.
