"I'm like, 'Look, it didn't work. Fine. Move on.' It's a tricky thing to figure out, which is when you ask yourself, 'Am I at the precipice of success or walking down the wrong road?' Because the greatest obstacle always comes right before the breakthrough. And you're always trying to determine which is which. Is this the greatest obstacle? Is it the breakthrough itself? Or is it time to go the other way? That's when you have to surround yourself with brutally honest people who will be like, 'Dude, you suck at this. Stop.' I have, like, two or three really strong data nodes that I know will tell me: 'I don't get it.'"
