René Crevel said this quote

Straight lines go too quickly to appreciate the pleasures of the journey. They rush straight to their target and then die in the very moment of their triumph without having thought, loved, suffered or enjoyed themselves. Broken lines do not know what they want. With their caprices they cut time up, abuse routes, slash the joyous flowers and split the peaceful fruits with their corners. It is another story with curved lines. The song of the curved line is called happiness.

~ René Crevel
