Richard Branson on Taking Chances: "When you decide to pursue an entrepreneurial venture, you have to confront your doubts and fears; sometimes you just have to go for it. Many times I have hesitated before launching a new venture or investment, even after my team and I have vetted it and we’re ready to go ahead. I’m lucky that I have a great network of friends and advisers to take soundings from.
If you believe that your personal training business can succeed, draw up a short plan describing how it would be different from other such businesses, how you would build it up and attract customers. Discuss this plan with trusted friends or advisers (make sure you ask people individually, and not as a group). Collecting and acting on this feedback is a crucial step before launching any business.
I can't help you make this decision without knowing more about your situation. However, I can tell you that when I have to decide whether or not to go ahead with a new venture, I have often found that intuition is my best guide. What does your intuition tell you? If you decide to go ahead, be prepared for a bumpy ride. Most entrepreneurs fail the first time they enter a market – or at the very least have to recover from a tricky scrape."
