I listened to a podcast the other day with Tony Robins and Theo Von. I realized that all these self-improvement people have at least one thing in common: they all have an extraordinary command of their own knowledge.

Robbins went fluidly from one concept to another for two solid hours: "here's 4 things about that", "there's five things you need to keep in mind here", "that's because of these six ideas". None of it was made up on the spot — he repeated a couple of these lists, in the same order each time.

Being able to speak fluidly, continuously, and authoritatively is such an advantageous skill.

I think he gets some flack for peddling snake oil, but his three of these, four of these, six of these all seem like extremely solid concepts to me.
