I'm in the middle of attempting to do a PhD and a startup at the same time but it's damn hard. I basically don't sleep. Meeting with my co-founder has become sparse as my research demands increase and it's really affecting our progress -- especially since I'm the coder. In short, if I want this to succeed, I have to leave, which basically I've decided to do at the end of this semester.
