It's very seductive and can creep in subtly. You got excited, put in an intense week of MLM'ing. You went all out. Then it creeps in. Next week you don't hit it as hard.
Network marketing is built on the concept of compound interest.
So it's hard to believe that by day 30 that penny has grown into millions . But it takes time for the compounding to take effect. If you spent your thousand bucks on day 18 instead of keeping it working for you, you'd never reach the 5 million dollar payday. And you'd have to start all over again from zero with a new penny and another 30 days. MLM works exactly the same way.
