I recently read Ben Horowitz's book "The Hard Thing About Hard Things: Building a Business When There Are No Easy Answers", it was great! I've read alot of management, marketing and strategy books but I can honestly say it is the only book I've read that captured any of my experience as a CEO or being in the inner circle with a CEO in a startup.
Einstein once said of his friend Kurt Godel http://en.wikipedia.org/wiki/Kurt_G%C3%B6del that his mere existence brought him happiness. I can say that about this book.
Ben captures five things that are integral to the role yet is never portrayed in the happy crap "small big company with freedom and payouts" media and journalism stuff...
1) Impossible odds and running out of money (again)
2) Peacetime vs Wartime CEO
3) Firing / laying off friends
4) Lonely decisions (esp: People Choices)
5) Overwhelming Guilt
Start ups are hard... it helps to be naive... why do people do it.... not all do...
