There's an old saying that a chain is only as strong as it's weakest link and this holds true for business as well. Anyone can buy a business license, print some business cards, pass out a few fliers and call themselves a company but to be a success you have to build a team of individuals that work as hard for your success as you do. This can, will, and has been screwed up by every successful businessman ever. I can't think of any great company that started and reached success with the same individuals, along the way people will get shown the door whether it be for personal reasons or strictly as a way of weeding out the dead weight.
A new business can expect to spend months if not years attempting to put together a team of like minded individuals. One of the biggest mistakes a new business owner can make is hiring friends and family. They will either take you for granted and think that they will never be replaced (fired) or they will start resenting any success you obtain. I myself have made that mistake in the past and have seen both results. My advice to any business just starting out is to assemble your team very carefully and learn to recognize that there will be times that you have to cut someone free for the good of the company. Do not hesitate at those times.
Now how strong is your chain?
