What you want to watch out for are "fast track" programs or pressure to have inventory that requires additional investment. Due to this practice, the law now requires MLM companies to buy back inventory, but that doesn't mean you want to be saddled with debt before you start and truly understand the business. Having a few popular products on hand can be nice, but don't fill your garage with products unless you know for sure, based on your experience in the business, that you can sell them.
Don’t give up, and don’t throw money into areas where you don’t have to. There’s no such thing as completely free marketing leads – you are always risking something, whether it is your brand, or your future earning potential. However, with good networking, passion, and the right people, you can achieve success. Talk to some mentors and more experienced marketers today, and see what they have to say for you. You may be surprised at how much you can bring in, with the right choices when you are getting started.
