Friedrich Nietzsche said this quote

“ Be not virtuous beyond your powers! And seek nothing from yourselves opposed to probability!...Shy, ashamed, awkward, like the tiger whose spring hath failed—thus, ye higher men, have I often seen you slink aside. A cast which ye made had failed...The higher its type, always the seldomer doth a thing succeed. Ye higher men here, have ye not all—been failures?Be of good cheer; what doth it matter? How much is still possible! Learn to laugh at yourselves, as ye ought to laugh!What wonder even that ye have failed and only half-succeeded, ye half-shattered ones! Doth not—man's future strive and struggle in you?Man's furthest, profoundest, star-highest issues, his prodigious powers—do not all these foam through one another in your vessel?What wonder that many a vessel shattereth! Learn to laugh at yourselves, as ye ought to laugh! Ye higher men, Oh, how much is still possible! ”
