Although one may not always get what they ask for, it is certain one will always learn for their past actions (positive effect). Learning is a process everyone endures as they get old; whether a lesson comes from a good deed or is the result of a wrong-doing.
One might learn that putting hard effort to achieve victory in a contest yields its rewards and provides a feeling of self-satisfaction, while realising that breaking into someone's home has its consequences once getting caught - witnessing the punishment on one's own flesh is very much different than hearing a condemn from parents.
No matter how old and wise, there's always something to learn.
