Be vary wary of people who declare that they're going to create heaven on earth, they almost invariably create hell.

It's one thing thinking something and another thing knowing it.

Lesson no. 17: Happiness is caring about the happiness of those you love.

And, like poor Phaedra, we fall in love not with who we want to fall in love with, but with one who moves us, and sometimes it is the last person we should fall in love with. Our involuntary choice is not always the right one, and sometimes it is actually the worst one, hence our suffering. And then, of course, there is the completely different situation of the loving people where, over the years, the love they once felt for each other fades and they can't go on. They feel their love dying, but are unable to bring it back to life.

People fall in love more easily when they are already troubled by another emotion because we know that any intense emotional state greatly increases the risk of falling in love.

Knowing and feeling are two different things, and feeling is what counts.

Sometimes happiness is not knowing the whole story.
