The most common high-pressure tactic is the lure of getting in on the ground floor. But in direct sales, a good opportunity is a good opportunity no matter when you get in. In fact, you're safer to go with a company that has been around for more than five years (the longer the better) than a start up. Any effort a representative makes to prevent you from studying the company, talking to others, and "sleeping on it" isn't someone you want to work with.
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.
