An old friend of mine called me earlier today to discuss his new business idea. I spent a couple of hours helping him flesh it out and create an action plan. However, like most would-be entrepreneurs, he had his priorities mixed up.
When most people want to launch their own business, they start by writing a business plan. Unfortunately, business plans are pretty useless in the early stages. You won't know enough to write a meaningful one until after you've launched your business.
