“Because, really, what was worse than lying wide-awake in the dark, watching your life drip away, one irreplaceable minute after another?”

Variant: You're alive only once, as far as we know, and what could be worse than getting to the end of your life and realizing you hadn't lived it?

Response to the question: "I have listened to you for many years and I have become quite good at watching my thoughts and being aware of every thing I do, but I have never touched the deep waters or experienced the transformation of which you speak. Why?"
1950s, Freedom From the Self (1955)
Context: The questioner wants to know why, after these many years of watching, he hasn't found the deep waters. Why should he find them? Do you understand? You think that by watching your own thoughts you are going to get a reward: if you do this, you will get that. You are really not watching at all, because your mind is concerned with gaining a reward. You think that by watching, by being aware, you will be more loving, you will suffer less, be less irritable, get something beyond; so your watching is a process of buying. With this coin you are buying that, which means that your watching is a process of choice; therefore it isn't watching, it isn't attention. To watch is to observe without choice, to see yourself as you are without any movement of desire to change, which is an extremely arduous thing to do; but that doesn't mean that you are going to remain in your present state. You do not know what will happen if you see yourself as you are without wishing to bring about a change in that which you see. Do you understand?

Variant: This is your life and its ending one moment at a time.
