Remember the advice your commencement speaker gave you at graduation? Me neither. Between praying my mortarboard would stay pinned to my head and the stress of potentially tripping after posing with the headmaster, I didn't have the focus left to pay attention to the advice that was supposed to carry me into adulthood (besides the importance of alumni contributing to the development funds).
However, in the decade or so since graduation I've collected a few nuggets of wisdom. So if you also spaced out during your commencement address, don't think you have to redo school or settle for "wearing sunscreen."
While great advice, real maturity goes beyond skincare to understanding God, others and yourself.
Created in the image and likeness of God, we will find true happiness when we are acting as he created us to act -- in love. In the Gospel of John, Christ explained, "greater love has no man than this, that a man lay down his life for his friends" (John 15:13).
Whether you're just graduating or have been hanging out in the real world for a few decades, real joy is never gained in serving yourself. Rather, it is found in love of God and those he created and a sincere gift of self.
