One problem with our current society is that we have an attitude towards education as if it is there to simply make you more clever, make you more ingenious... Even though our society does not emphasize this, the most important use of knowledge and education is to help us understand the importance of engaging in more wholesome actions and bringing about discipline within our minds. The proper utilization of our intelligence and knowledge is to effect changes from within to develop a good heart.

Disciplining yourself to do what you know is right and important, although difficult, is the highroad to pride, self-esteem, and personal satisfaction.
