There are people who prefer to say “Yes,” and there are people who prefer to say “No.” Those who say “Yes” are rewarded by the adventures they have, and those who say “No” are rewarded by the safety they attain. There are far more “No” sayers around than “Yes” sayers, but you can train one type to behave like the other.
Is improvisation a skill that can be learned? You bet. You may be surprised to learn that it is actually a method of working. There are rules of conduct about what to do and how to pay attention while you are creating in the spur of the moment. (For example, an improviser learns to memorize a name the first time it is mentioned.)
