If you are planning to operate a home business that sells a product, you have to find a product you can stand by. This means a product that you are convinced is worth the money, is manufactured well, and one which you would use yourself. The actual product you're selling isn't nearly as important as your firm belief that it's the best that can be found for the price. Which product? It doesn't matter if it's cosmetics, apparel, jewelry, home products, or home theater popcorn machines, as long as it's something that excites you.
Once you're excited about the product, those you encounter will share that excitement and be more interested in it.
