Everybody wants to have their idea validated by someone else. But be careful about wagging it all around the office in search of approval. Pick a couple of people whose opinions you trust and show it to them. They’ll give you a read on it, and may have comments that make it better.
If your trusted advisors tell you the idea stinks, then be willing to walk away from it. If you’re not, then don’t go looking for outside opinions. You have to be willing to hear the bad news as well as the good.
