“Did you ever see an unhappy horse? Did you ever see a bird that had the blues? One reason why birds and horses are not unhappy is because they are not trying to impress other birds and horses.” (Ai vazut vreodata un cal nefericit? Ai vazut vreodata o pasare care sa fie trista? Motivul principal pentru care pasarile si caii nu sunt nefericiti este ca nu incearca sa impresioneze pe celelalte pasari sau pe ceilalti cai.)
Dale Carnegie
