Some guys sell motivational and how-to-get-rich books on the street.

Nevertheless, they hustle on the streets, year after year, selling books only a few people care about.
Why aren’t they rich by selling books that show the way to wealth? You may ask.

They usually are poor and look gloomy.

Recently, in Ghana, some women sell female body enhancement drugs. These drugs promise to make certain parts of the body firmer and bigger to attract men. Yet, these sellers look nothing like what’s on the labels.

You have to use what you offer to people, reap the benefits and become living proof.

That way, people will trust you.
