Regardless of how many years you live here on earth above the ground, even if its 100 years, remember that the amount of years of years you will live under the ground in your grave is more. The Hereafter is longer and more complete so plan accordingly. Recall the verses: "But you prefer the worldly life. While the Hereafter is better and more enduring" [Translation/Meaning of the Quran, 87:16-17]
