I'm pretty good at sticking to what I know. You don't see me social commentating on health-care or presidential debates. I talk about what I know because I'm petrified of being wrong.

Eighty-five per cent of the crowd is going to fall in love with me - they're going to feel it, wow. But fifteen per cent are going to think, 'This guy is obnoxious.' I spend enormous time with them - every negative review of 'Crush It!' on Amazon has a response from me - and I can probably bring back ten of the fifteen.

We're not really good at knowing what we want, and we are quick to say 'this sucks'. That's where the opportunity lies.

You need to spend all of your time and energy on creating something that actually brings value to the people you're asking for money!

I measure my success by how happy I am, not how big the business is or how much money I've made.

Stop whining, start hustling.

We are living at the beginning of the humanization of business.
