Learning can never stop. Just when we thought we know it all, there is something new to learn.
We are not perfect beings. We are human and mistakes may abound.
There are new things to learn everyday. Lessons abound on marriage, emotional management (temperament), personality development and behavior, etc.
Maturity is realizing that one is prone to mistakes, and self-correcting the moment you realize those mistakes is maturity.
Be ready and willing to learn your lesson so you can live a better life. You will be happy and you will be able to prove your worth in the society.
