"Opportunity just exists in the air for a few minutes. If you don't obey your gut feeling right away,..." — Ken Hakuta

Speed is vital. You got to strike fast. Fads have short lives, and you got to get what you can - like the case of the Pet Rock.

There are conventions for people with serious, boring inventions, but fad inventors need help. You need someone to talk to. You just can't tell your friends you're going to invent a pet rock and mortgage your house to pay for it. It's embarrassing... risky mentally. Your friends think you're crazy.

A true fad has little utility beyond its entertainment value. Think of the Mood Ring, the Pet Rock, the Slinky, Silly Putty.

I wouldn't finance a fad if I were a banker.
