Youth means a kind of courage to overcome timidity, a kind of adventurous desire to overcome ease. This is more common in a 60-year-old man than in a 20-year-old boy. No one grows old just because of age. We grow old by giving up our ideals.
Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns youth to ashes.
Whether 60 years old or 16 years old, everyone has the temptation of miracles, a childlike desire for the future and the pleasure of enjoying life. In the center of your heart and my heart there is a wireless station: as long as it receives messages of beauty, hope, joy, courage and strength from men and women, you will remain young forever.
When the aerials are down, and your spirit is covered with ice and snow, cynicism and self-abandonment arise. Even at 20, you are old. But as long as your aerials are up and you catch signals of optimism, there is hope that you will die young at the age of 80.
