Just read couple of stories in “Stay Hungry and Stay Foolish” book. It is a fantastic book and I would recommend. Here is my crack on it.
According to book, there are four major aspects to any successful venture. First is financial where individual has to deal with its Security and Support. Second is Focus which is that individual’s desire to Do It and his/her capability to perform. Third is ability to Ideate a solution with future vision. And last is social ecosystem to support and complement the effort.
