A similar theme, this time from the Christian tradition:
Nothing lasts. No single thing can consume our entire life’s meaning. No single thing can give us total satisfaction. Nothing is worth everything: neither past, nor present nor future. It isn’t true that the loss of any single thing will destroy us. Everything in life has some value and life is full of valuable things, things worth living for, things worth doing, things worth becoming, things worth loving again. It is only a matter of being detached enough from one thing to be open to everything else.
The essence of life is not to find the one thing that satisfies us but to realize that nothing can ever completely satisfy us.
