quixoticity,

as mentioned, is not a word.

quixotic, however, goes follows

quixot'ic a. idealistic but impracticable, foolishly or
absurdly generous, chivalrous, etc

ok.

i can only identify with the first two, being absurdly sure that i'm in no way overly generous or chivalric (is that a word?) unless you count asphyxiation in that US$15,000 Tommy Pickles costume.

two out of five is not bad
