My wife recently started her own family and pet photography business. I just printed out her first invoice. It’s an amazing feeling.
We definitely “bootstrapped” it during the startup phase (this is a term I learned from Seth Godin’s fantastic e-book about entrepreneurship The Bootstrapper’s Bible).
She’s still just getting started, but I anticipate that she’s going to be pretty successful in the coming years due to her diligent work ethic, perseverance, and the fact that this was something she was supposed to do.
