2) Knowing the consequences of the behavior. Before you dare to do something, it would be very useful to project the possible consequences of your actions; whatever they are. If consequences are positive, then proceed. But if consequences are negative, do not even try it. If you are not prepared to handle the consequences, then, don't do it.
