Yourself. 13 years, 14 in December, as freelancer, I get to work directly with people who have problems, my software really helps them instead of being an internal tool that will get reinvented in 5 years at big corporations. I choose my own projects, I am constantly learning in different industries, meeting (both virtually and in person) people from all 5 continents and while the pay is great my biggest motivator is that I can spend time with my family and raise my own kids. I do realize I'm one of the lucky few.
