Man is more himself, man is more manlike, when joy is the fundamental thing in him, and grief the superficial. Melancholy should be an innocent interlude, a tender and fugitive frame of mind; praise should be the permanent pulsation of the soul. Pessimism is at best an emotional half-holiday; joy is the uproarious labour by which all things live.

G.K. Chesterton

I want to learn to live like that.
