If you want to close more sales, wield more influence, and expand your network, you only need one thing:

Conviction

Whoever seems more certain of themselves wins.

The best way to have conviction is...

To actually put in so much work, do so many reps, and have gone through so much trial and error that you know for a fact you have the goods.

Most want to skip this step which is why nobody believes them when they pitch their ideas, products, and services.
