Keep love in your heart. A life without it is like a sunless garden when the flowers are dead. The consciousness of loving and being loved brings a warmth and a richness to life that nothing else can bring.
A silent look of affection and regard when all other eyes are turned coldly away-the consciousness that we possess the sympathy and affection of one being when all others have deserted us-is a hold, a stay, a comfort, in the deepest affliction, which no wealth could purchase, or power bestow.
To resist the frigidity of old age, one must combine the body, the mind, and the heart. And to keep these in parallel vigor one must exercise, study, and love.
