In a world full of websites and e-books and apps, the moment you look and sound like everyone else, you're dead. - Ramit Sethi

The major turning point for me was when I got serious with my girlfriend. She made about a third of what I made, but she had about a year's salary saved up. I was ashamed to have $40,000 in debt, so I started applying the IWT principles to pay down debt and accomplished that inside two years.

Most busy people want to mentor someone great

Marshall Goldsmith, one of the world's top executive coaches, put it to me this way: "Your biggest challenge [is] customer selection. You pick the right customer, you win. You pick the wrong customer, you lose. Focus on helping great people get better." Ultimately, this is your business. It's up to you to run your business as you see fit, and serve the customers you want to serve. In our experience, business is the most fun (and most profitable) when you focus on helping great people get better.
