Well the schedule looks like its not really "hard" work. When i do all these things in my startup i feel like i am not really working, i only have the feeling of accomplishment when i write code and improve the product. Marketing and Biz dev sure is very important but personally i dont feel like i get stuff done when doing it, which might be bad. Then again i couldnt put in 16 hours of work everyday, thats insane and i cant believe hes doing that for a very long time. After 10-12 hours of coding and working on technical things, i am done for the day. Some sport in the evening to stay healthy and blow off steam and thats it. And even that leaves me with very little real life during the week, which sometimes is frustrating.
