There’s nothing more likely to get him interested in doing something than to be told it couldn’t be done. If you were to meet with someone who said, ‘Oh, that can’t be done,’ you’d probably say, ‘Okay, I won’t do it then.’ Richard would say that those people wouldn’t succeed in business.
If they tell you "it can't be done" -- people are always telling writers this -- do it anyway.
I'm a huge fan of WIGs: Wildly Improbable Goals.
Set a WIG today. Show them it can be done by doing it.
