I am going to have to jump on the "PASSION" band wagon also. I started my first business in elementary school (selling candy out of a duffel bag)
. I have had other businesses that I haven't been passionate about. I only got into them for the money and that was a mistake. I found that money is not a good enough motivation. I soon lost motivation for the business altogether and have since taken a very different approach. I need to be passionate about something to get involved with it and it makes me much happier.
