There are no great limits to growth because there are no limits of human intelligence, imagination, and wonder. Sure maturing out of our childhood into adulthood is a major process in our life, and we learn things that we will use for the rest of our lives such as manners, correct etiquette, job skills, and a basic education, but maturing into our real selves is a process that takes a life time.
What makes Superman a hero is not that he has power, but that he has the wisdom and the maturity to use the power wisely. Maturity is not measured by age. It’s an attitude built by experience.
Maturity is achieved when a person postpones immediate pleasures for long-term values. When we conquer maturity we are not just passing and age milestone, because quite in fact our age doesn’t determine our maturity. Maturity is about being able to understand what to do in certain situations, and despite your age, we can become more mature every single day of our lives.
As we grow older we should always seek the knowledge it takes to become a better person as each day passes on. Being mature requires us to seek wisdom, and not only be knowledgeable but we should also be able to apply whatever knowledge we gain to our everyday lives. Your intelligence is measured by those around you; if you spend your days with idiots you seal your own fate because you don’t need to know all the answers. No one is smart enough to ask you all the questions.
