Criticism may not be agreeable, but it is necessary. It fulfils the same function as pain in the human body. It calls attention to an unhealthy state of things. Winston Churchill
Watch out for the joy-stealers: gossip, criticism, complaining, faultfinding, and a negative, judgmental attitude. Joyce Meyer
In marriage there are no manners to keep up, and beneath the wildest accusations no real criticism. Each is familiar with that ancient child in the other who may erupt again. We are not ridiculous to ourselves. We are ageless. That is the luxury of the wedding ring. Enid Bagnold
I much prefer the sharpest criticism of a single intelligent man to the thoughtless approval of the masses. Johannes Kepler
