Nothing thwarts happiness so much as the memory of happiness.

Some memories are realities and are better than anything that can ever happen to one again.

Our memory is a more perfect world than the universe: it gives back life to those who no longer exist.

There is no greater sorrow than to recall happiness in times of misery.

There is no worse sorrow than remembering happiness in the day of sorrow.

Happiness isn't something you experience, it's something you remember.

There is no greater sorrow...than to be mindful of the happy time.

"To me she said: "There is no sorrow greater than, in times of misery, to hold at heart the memory of happiness.

Nothing is more fatal to happiness than the remembrance of happiness.

...and memory, however sad, is the best and purest link between this world and a better. But come! I'll tell you a story of another kind.

They say that Hope is happiness
But genuine Love must prize the past;
And Mem'ry wakes the thoughts that bless:
They rose first — they set the last.

And all that mem'ry loves the most
Was once our only hope to be:
And all that hope adored and lost
Hath melted into memory.

Alas! It is delusion all — The future cheats us from afar:
Nor can we be what we recall,
Nor dare we think on what we are.

"And if all could with one voice be asked whether they wished to be happy, there is no doubt they would all answer that they would. And this would not be possible unless the thing itself, which we call "happiness", were held in memory."

No hay mayor dolor en el infortunio que recordar el tiempo feliz.

The bitterest of woes Is to remember in the midst of pain A happy past;
