They are not that secret, but they are powerful and worth to keep them in mind. In an interview given to Sydney Morning Herald he listed his business rules:

  1. Aim for the hole, not the green.
  2. Don’t spend a dollar unless you know damn sure you’re going to make at least a dollar back.
  3. Focus, focus, focus.
  4. Remember: no one is going to hand you success on a plate. It’s up to you to make it happen.
  5. If you’re not going to do it now, when? When you’re 60?

And another gem is this: people are always motivated to buy pain killers, but they are reluctant buyers of vitamins.

These are good solid principles which he seems to practice. His business has grown at a rapid rate and he is on his way to achieve his dream of becoming as large as Amazon or Google.
