Daniel relates a good approach to take when considering our own mortality. He writes:
If you google the words dying well, you will find all sorts of things, from euthanasia supporters to spiritual advice to tips on spending your last days well. It goes on and on. What you don't see is people reminding us to live in our baptism, to live in daily repentance, to live the sacramental life, to live our lives in our vocations. All of these things help us to prepare to die well. Ultimately, however, as much as all the repentance, the Eucharist, and everything else I mentioned helps us, to die well is to cling to our baptism.
