I like that exercise and spend time with family part, emotional drain is cause for productivity lost, bad decisions. The basic definition of start up is to get it running, building everything all along, customers, product, technology, architecture, user experience, UI Design, re-iterate the learning and fine tune again and again. Mentor is not needed for technology advise or adding business value or evaluating user interface, instead a mentor helps to drive the startup crazy, throw the founders into kickboxing stage, let them fight and learn than learn and fight.
