Give away everything that you know. For free. But charge for implementation or your product. Instead of promoting yourself, promote your friends lavishly. Since they'll promote you, which is way more powerful than anything you could ever utter about yourself. Teach from your direct example of what's worked for you. And listen to advice only from people who are openly sharing their direct experience-- and who have already achieved what you want. Become a public figure not because you want to be famous, but because you want to serve others on a massive scale. Via Dennis Yu of Digital Marketing With Dennis Yu
