I quit my job last November. In January I started my own business doing machine learning consulting. It took off slowly, until July I was not making too much, only small clients. Then business started taking off and now I'm too busy for my own good. I learned a lot. Biggest lesson is that I need to charge more. A lot more. Another thing that surprised me was what brought in the most income, both in absolute terms and in a per hour rate, so I'll have to reconsider my positioning and marketing strategy for next year. And I love what I'm doing and I feel like growing a lot. There have been many moments where I doubted things (The Dip as Seth Godin calls it), but somehow I got over them.
