4. The 10-to-1 Rule of Profitability

If you want to make $1,000, make sure you first contribute $10,000 worth of value.

If you want to make $20,000, make sure you first contribute $200,000 worth of value.

This is my 10-to-1 Rule of Profitability.

You get back in profit 10% of what you give freely, 10% of the usefulness that you provide, the service you offer up purely out of the love of being helpful.
