It's been my plan since high school to figure out a way to work for myself eventually, though I was very grateful for my job at Google. After the initial 2 years, my work at Google began feeling more routine (I chose to stay in the same team, and I was getting better at my job at the cost of learning fewer new things). I left after 4 years after deciding that I had learned enough and saved enough to move on to what I've viewed as the next stage.
