Happiness: being able to forget or, to express in a more learned fashion.

The advantage of a bad memory is that one enjoys several times the same good things for the first time.

Let old ones go. Dont be a memory-monger!
Once you were young──now you are even younger.

Blessed are the forgetful; for they get the better even of their blunders

What we do in dreams we also do when we are awake: we invent and fabricate the person with whom we associate -- and immediately forget we have done so.

Man does not strive for happiness; only the Englishman does that.
