Man, am I guilty of this myself. I'm *always* afraid to talk about a new fab idea I might have because I'm afraid someone is going to steal it. So I keep it a secret...and make everyone I tell swear that they'll keep it a secret too. Then we're all so busy keeping the secret about my million dollar idea, opportunities are being missed, networking possibilities are being lost and buzz is decidly NOT being built.
There is a great article on this very topic over on I will teach you to be rich which basically says: get the heck over yourself.
I'm busily trying to get into this frame of mind myself as I get ready to launch Paper Bride's little sister, Paper Mama. There I said, it: PAPER MAMA. Coming soon to a www near you.
