Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.
Youth means a tempermental predominance of courage over timidity of the appetite, for adventure over the love of ease. This often exists in a man of 60 more than a boy of 20. Nobody grows hold merely by a number of years. We grow old by deserting our ideals.
Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns the spirits back to dust.
Whether 60 or 16, there is in every human being's heart the lure of wonder, the unfailing childlike appetite of what's next and the joy of the game of living. In the center of your heart and my heart there is a wireless station: so long as it receives messages of beauty, hope, cheer, courage and power from men and from the Infinite, so long are you young.
When the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old, even at 20, but as long as your aerials are up, to catch waves of optimism, there is hope you may die young at 80.
So many people are judged by their age. You are either too young to do certain things or too old. But I think that age is a state of mind.
Yes, I know that there are somethings I do more slowly these days, but I still do them. I’ve seen some young people that act as if they are older than I am. But then I can’t judge them either, because we never know what others are going through.
There are a lot of things that will age people faster than others. I try to keep the following quote in mind
You are as young as your faith, as old as your doubt; as young as your self confidence, as old as your fear; as young as your hope, as old as your despair.
