I recently found out about your Goal of Life. I know! I know! Who am I to talk about your goals? True, I don't know anything about your goals. But when it comes to your Goal of Life, I just found out about it.
Let's say your Goal of Life is Goal-A, whatever that may be. Imagine you achieve that. Just imagine. What next? Life continues...What Next? Well, then you would have to have another goal set, say Goal-B. That makes Goal-B the Goal of Your Life (not Goal-A). That too when fulfilled, will have to replaced by Goal-C. And so on, there is no end to it.
So, with this mind-experiment, we figure that "the Goal of Life is the one whose fulfillment leaves nothing else to be desired." And that definition holds good for me, and you and everyone else. I figured this out in the recent retreat held by our Swami at Ridgely Manor, NY. The title of the retreat, quite meaningfully, was "Stop not till The Goal is reached."
