There are so many great business opportunities available that it can be tempting to jump from one opportunity to another. However, the price you will pay is that you will never develop a long-term business strategy and you will never become known as an expert in any one area. Remember this phrase, "Do not try to be all things to all people." You should focus on one or two target markets and then build a business plan focused on reaching these targeted markets.
Find a niche that suits your interest and expertise.
