I turned in my two weeks notice over a month ago. No, I didn't have another job lined up. No, one of my many malnourished ideas didn't suddenly get venture funding. No, I didn't win the lottery or have a rich aunt die. I quit because the time commitment at work began to routinely crest over 70 hours per week. I quit because there wasn't much recognition. I quit because there weren't any promotions or pay raises anywhere in site.
I quit because I wanted to.
