Some quotes by Epicurus:

> Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for.

> The present moment is the only moment available to us, and it is the door to all moments.

And this absolute banger:

> Death, the most dreaded of evils, is therefore of no concern to us; for while we exist death is not present, and when death is present we no longer exist.
