I attract a crowd, not because I'm an extrovert or I'm over the top or I'm oozing with charisma. It's because I care.

It's not how many followers you have, it's how many care. It's not width, it's depth. It's not how many impressions you get, it's how much attention you get.

First of all, when building a brand you have to know who you are, what you are, and what you stand for. That's clichéd marketing-bullshit jargon, but it does matter. It helps. You have to know who you're targeting. I think too many people fight the market. There are certain people who are never going to want your stuff no matter what you do. There are certain people are never going to love me because I curse and I have bravado and I'm a Jersey boy and I'm brash and they won't take the time to see the humility and the patience and the truth. They shouldn't.

I definitely think there's some way to understand how people emotionally feel about somebody, but I don't think data collects it. They're not going to click your bit.ly link or click your TweetMeme retweet every time.

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.

I'm concerned a little bit with the culture of celebrating the fundraise. My dad taught me that when you borrow money it's the worst day of your life.

I find it fascinating that a lot of business books that do well are from people who've never made any money in business.
