I am with you, certainly I have my startup almost always in my mind, and I "work" (reply emails, research stuff, etc..) at strange hours. But I have family and my time with them and with friends is very necessary. In fact I have noticed that certain matters need their time and it doesn´t matter how much you push them, they are not going to take of faster. There is a kind of social tempo that an idea needs to engage, I am learning to relax and wait for those waves in order to ride them (there is still a big proportion of work that needs to be done and that can accumulate very fast if you let the time past).
