Getting discouraged is a total waste of your time. - John Cleese

If you want creative workers, give them enough time to play.

You can do the creation and then criticize it, but you can't do them at the same time. So if you're worried about offending people and constantly thinking of that, you are not going to be very creative. So I think it has a disastrous effect.

Put simply, you can’t ask your unconscious a question, and expect a direct answer — a neat, tidy little verbal message.
