This can be guided by knowing one's purpose in life, and by knowing that life does not end when this mortal lifetime ends, but we will actually continue to exist; and it is possible, based on our individual choices, that our learning, service, and growth can continue. For me, this helps take the pressure off. I wrote how I know this, at my simple web site (in profile). There are ways to use our time that brings happiness in things that last and are not transient. A scripture says: men are that that they might have joy. Another says that what we learn by our diligence in this life will remain with us in the world to come. So it's definitely not a waste, to learn, and serve others with our time.
