"Whatever vocation you decide on, track down the best people in the world at doing it and surround yourself with them. Aim high and be ridiculously persistent. Your happiness is at the intersection of your passions and learning from great people. Working at a big company sucks--avoid it. Smaller companies are 10 times better for learning. Be generous with your time and money--it has an amazingly fast payback. Be in the moment with everyone you love--and this frequently means tuning out work completely. And drive slow in parking lots."
