I do have a friend who happens to be the over convident type of looser. He alerts really on what he heard somewhere years ago, never embraces new ideas. I hope he changes one day.
For me I can be catigorized under both the smart looser and the unlock once, depending on the situation.
I am the opened to new idea type, I try things differently and do not underestimate any one bringing new ideas no matter how small the person is. But in a situation where it seems like ideas ain't coming and all ideas tend to fail, I think of it as being unlock
