One Day

How can I accept death? I know it has to happen one day but how can I accept it?
Life would be easier if I could accept it. Plus I plan on enlisting in the Marines after High School.
Thanks.
Contemplate death. The Samurai were totally fearless of death due to this, as Yamamoto Tsuretomo wrote in his book Hagakure [way of the Samurai]:
“Meditation on inevitable death should be performed daily. Every day when one’s body and mind are at peace, one should meditate upon being ripped apart by arrows, rifles, spears and swords, being carried away by surging waves, being thrown into the midst of a great fire, being struck by lightning, being shaken to death by a great earthquake, falling from thousand foot cliffs, dying of disease or committing seppuku at the death of one’s master. And every day without fail one should consider himself as dead.”
