Being an entrepreneur means that you are sort of inventing something new. You're giving birth to a company. You're giving birth to a new product, a new service. And that's always exciting.
Of course, spending time with family is always good. I love the outdoors, so if I get a chance to go out and hike or bike around, that's always great. If I don't have time to leave, just listening to some music that I love reenergizes me and gives me that break I need to go back to whatever it is I'm doing.
