From Alan Watts’s intriguing and challenging The Book On the Taboo Against Knowing Who You Are:
Unless one is able to live fully in the present, the future is a hoax. There is no point whatever in making plans for a future which you will never be able to enjoy. When your plans mature, you will still be living for some other future beyond. You will never, never be able to sit back with full contentment and say, “Now, I’ve arrived!”
Your life is now. The challenge is to live where your life is and not where you think or hope it’s going to be in the future.
