None so blind as those who won't see.

Beggars should be no choosers.

There are none so blind as those who will not see. The most deluded people are those who choose to ignore what they already know.

Though he love not to buy the pig in the poke.

I know on which side my bread is buttered.

Let the world wagge, and take mine ease in myne Inne.

Make hay while the sun shines.
