There are books too. Since we are all familiar with dishonesty, and lack of integrity, it may be more challenging to try and understand what real integrity entails. Integrity is not a character trait. It is a behavioural description. Just as people may be creative, and still not be inventors, people can be honest but not possess integerity.
Creativity is, perhaps, a trait.
Being an inventor means you already USED that trait, and created something worthwhile. Behavioural descriptions, like behaviour itself, usually reflect a multitude of traits. Indeed, I guess we all know jokers who are on the verge of being clinically depressed. Honesty is a good place to start, but it too is a fuzzy concept. It is best to start with more simple things.
