It's hard for many people. There's plenty of theories out there that state that much of what we do and much of what we by are motivated by our fear of death and our desire to ignore it.
The best way to face death, however, is head on. Look at yourself in the mirror and firmly remind yourself you will die. Find some way to remind yourself of this every day. St. Thomas Aquinas is said to have kept a skull on his desk to remind himself of his morality. At first, you will feel many emotions, fear, anxiety, depression, anger. You may rush around for a bit, trying to get things done. But the more you think about your death, the more you meditate on it, eventually, things will settle down, and you'll ask yourself the right questions: "What do I want to be remembered for? What do I want to achieve before I die?"
