Answer: Accepting responsibility for your feelings
Explanation: The fact that every action has its consequence is what is learned from early childhood. With the growing up and the complexity of living conditions and relationships and environments, this fact is slowly shifting into oblivion. Then we tend to blame others often for our own feelings, which may also be the result of some of our previous actions.
Yet there are people who understand the connection between action and consequence and are willing to accept responsibility for their own feelings. It is true that external events triggered our feelings, but their cause, that is why we feel that way, is certainly within us.
