To get everything you want is not a good thing. Disease makes health seem sweet. Hunger leads to the appreciation of being full-fed. Tiredness creates the enjoyment of resting

It is hard to contend against one's heart's desire; for whatever it wishes to have it buys at the cost of soul.

Nothing is, everything is becoming.

Everything changes but change itself. Everything flows and nothing remains the same... You cannot step twice into the same river, for other waters and yet others go flowing ever on.

Knowledge is not intelligence.

You cannot step twice into the same river.

If we do not expect the unexpected, we will never find it.
