Whichever road you choose, it will involve serious planning. Unless you have ready funds at your disposal, getting finance is the next major challenge and cannot be attempted until your business plan is in place. You will need to prepare funding proposals and applications for loans, venture capital, and funds from angel investors. This is make or break time.
Many people think just getting started is the hard part - and it is hard.
But where many businesses stumble is not in the planning and financing stages but in implementing their business plan. Why this is so is not certain. There are various hypotheses including the idea that ideas people and implementation people are two very different breeds and it is highly unusual to find one person who can do both. More likely though, is the simple fact that implementation requires such a broad range of skills that no one person can possibly be adept at all of them. The real challenge and skill of the entrepreneur, then, is to recognize what you do well and then appoint employees or subcontractors to do the rest.
