What's Your Secret Source?

When I try to understand your journey and prepare for this podcast, I tried to find what's your secret source? How come somebody like you can have those two mega hits and a couple other hits in between? And then I suspect maybe it's maybe the fact that you must be the product guy. You're not the entrepreneur that's great at raising capital or selling a big vision. Slack raised a couple billion dollars, but it was in the time in history to raise lots of money.
