Being an entrepreneur is fun & exciting. Even though you are doing work and working, it feels like a hobby. Because it is you and your reputation at stake--your livelihood is in your own hands. Do or die. You are your own boss and you don't have some dickhead piece of shit (POS) breathing down your neck at every error. And much to your surprise, many of your customers are understanding and lenient--as long as you're honest.
If you're a POS dickhead, you'll probably fail in the long run.
