beggars can't be choosers.

Don't look a gift horse in the mouth. I have a bone to pick with you. If the shoe fits.

Buy low, sell high Never eat yellow snow

Your guess is as good as mine.

"All animals, except man, know that the principal business of life is to enjoy it--and they do enjoy it as much as man and other circumstances will allow. He has spent his life best who has enjoyed it most; God will take care that we do not enjoy it any more than is good for us."--Samuel Butler, "The Way of All Flesh"
