There are 5,000 different types of small businesses. You can make a comfortable living, and realize your long term financial objectives, with most of them. The business that you choose doesn’t matter. Find people who are already successfully doing what you want to do and model yourself after them.
The Chinese have a saying, “Do something that you love and you’ll never have to work again.” So, why not start looking at business opportunities based on a talent, interest, or skill that you may have, and you may find yourself loving every (work) day.
Of course, the opposite is also true. If you can’t find people who have ever been successful at doing what it is that you want to do, then be cautious. Make that very, very cautious.
