Over the years I've learned many things from following Adams' blog. He recommended Cialdini's books on persuasion, which are a must read for all sales people and all entrepreneurs (because we are salespeople, like it or not). His financial advice [1] is rock solid, and his latest book on goal-oriented vs. systems-oriented thinking was also an eye-opener.
TLDR: I like the dude.
