"Q: How do you know when you’re thinking too big or aiming too high (if that’s even possible)?"
"A: In the mid-90s I had an idea that lasted about the amount of time it takes to drink two beers. I say this because I had the idea at a bar and it was quickly squashed by the two friends I was with

That would’ve been simple and not taken too much time before there was some payoff."
