I was about to say moving fast might be a necessity of marketing. Then I recalled Apple's 1984 commercial. It's timeless for their brand.
Gary's advice works especially well for people who like to "learn while doing" - the types that don't want any lesson or book and just dive in face first - when attached to this statement, "I'm obsessed with intent. It's the 'north star' of every decision I make."
If you don't know where you're going and why you're going that way making any decision at all is brutal. Doesn't matter how fast or slow you think. So his point on intent is key for making decisions faster.
One more thought on Gary - he's like Edison rather than Tesla. And since we know his life's dream is to buy the Jets (which I think he'll achieve and hope he does) it serves him well to be more like Edison (who made all the money) than Tesla (who died broke but well remembered and loved by the nerds).
