Youth is not a time of life – it is a state of mind. It is not a matter of ripe cheeks, red lips, and supple knees; it is a temper of will, a quality of imagination, a vigor of emotions; it is a freshness of the deep spring of life. Youth means a temperamental predominance of courage over timidity, of the appetite of adventure over love of ease.                 Samuel Ullman, 1840 – 1924
