I would start a business that takes advantage of my ability to be a jack-of-all-trades. I've been writing professionally since I was 17 years old, and my work has been featured in publications like [name of publication]. I'm also an avid photographer, and have spent many years documenting events and people in my community. I can also program. I have experience working with Python, Ruby, PHP and MySQL.
In short: I'd start a company that uses my skills as a writer and photographer to create beautiful visual reports on events. The goal would be to help people document their lives and share them with the world without having to spend thousands of dollars on professional photographers or videographers.
