Turn your weaknesses into a strength.

I think of Scatman John, the musical legend when I write this. Scatman had really bad stuttering during his real life. He decided to do something about it and took up the musical form scat, using his stuttering as the basis of his music.

A key in business to turn any weakness into a strength is to see how that weakness can generate into a solution for other people's needs, and thus be able to sell it.

An example would be a bad habit you are able to succeed inspite of. If you are lazy, and make money, you show people you are lazy but still make money.
