The best insights don’t necessarily come from the best people.
Good advice is about the content of the ideas, not the character of the spokesperson.
The question to ask, when evaluating advice, is not “Who is the source and is he worthy of my trust?,” but rather “How do these concepts weigh against my own personal experiences and experiments?”
Strong ideas are capable of standing on their own feet.
If an idea is worth following, it’s worth fact-checking.
