Life is too short to drink bad wine.

Johann Wolfgang von Goethe (1749-1832) German poet, statesman, scientist
(Misattributed)

Often attributed to him, but not found in Goethe's works. The attribution, though, may come from translators' commentary on Goethe's West–Eastern Diwan, "The Book of the Cup-Bearer" (1819/1827), that refers to a poetic passage as deriving from Diez's 1811 translation of the Book of Kabus (Qabus):

It comes to this, that it is a sin to drink wine. If though, then committest sin, commit it at least for the best wine, for otherwise wouldst though on one part commit sin, and on another drink bad wine. By God! that would be the most sorrowful among sorrowful things. [tr. Rogers (1890)]

It so happens that wine-drinking is a sin. Hence, if you do commit this sin, do it at least with the best wine; otherwise, you'll commit the sin, on the one hand, and on the other, you'll drink bad wine. By God! That would be the sorriest of all sorry things. [tr. Ormsby (2019)]
