Guy Kawasaki has become (always was?) quite the guru. 'How To This', 'Ten Biggest That'. Next thing you know he will be blurbing the ROM and have his own Fijian resort.
But lets face it, at the end of the day what you really want is just to be RIGHT. I tell you how in 3, count them, 3, easy steps:
Rightness only really exists in relation to wrongness, so compared to the competition:
1. Do more research, and gather more information.
2. Think more deeply and critically.
3. Limit the scope and detail of your answer to what you do know.
That's all there is to it!
