I once new someone who informed me that they did not need to learn, grow and mature any longer. They were of sufficient age and experience that growth, learning and maturation was neither necessary nor desired.
I can’t express how much I disagreed with those sentiments. I truly believe that we are always learning and growing whether it is perceivable to us or not. The key is in understanding and assimilating what we have learned and then utilising the resulting growth and maturation to benefit ourselves and others.
For when we cease to learn and to grow, we fail not only ourselves but the world around us.
Adiuva me verterem figuram mundi 
When we fail to embrace growth – we lose!
