What I did the first time: When I moved to San Francisco, I met people who made their livings selling jewelry and pottery to tourists at Fisherman's Wharf. They had fantastic days where they made hundreds of dollars selling their art on folding tables.
I thought this would be a great way for me to make money, although crafts was not an intuitive choice for me. I liked art, but I was terrible at drawing. Soon I found myself making jewelry inspired by my paintings of San Francisco's landmarks and fantastical cats.
I never hit the jackpot that I'd imagined was waiting for me as a craftsperson, but I stuck with the business for the long term because making art fed my soul. Over time, I became much better at drawing, though it still doesn't come easy to me.
My learning curve was incredibly steep, though, and that cost me when I initially started my business. It took me years to go from clumsy amateur to skilled artist. As a writer, I was able to move very quickly out of the novice phase, because writing comes naturally to me.
What I did the second time: I have wanted to be a writer ever since I learned to read. In 2013, I quit the job I had taken after closing my crafts company and went to work full time as a freelance writer. Within a few years, my writing business became more financially successful than my crafts business ever was. I went from a green newcomer to a skilled writer very quickly, because I am doing the work that I was meant to do (and spent many years training for, from starting a neighborhood newspaper at age 10 to my college major in English and creative writing).
Find the thing you were meant to do, and you'll find the best starting point for your business.
