Great article! I admire him for not giving up and even becoming a successful entrepreneur under these severe circumstances.

Yet, I'd like to post a warning here. Putting the metaphoric gun to your head, as the article suggests, may sometimes be the only feasible option, but it can also lead to psychological problems later on. Not everything works better with force. In fact, there are things that require the opposite. It's easy to unlearn that when you put yourself under constant force and pressure, and your success becomes based on that solely.
