Psalm 90:12 KJV So teach us to number our days, that we may apply our hearts unto wisdom.
When young, we think we have our whole lives ahead of us. But just as today is the “Someday” we thought about some time ago, the future will come as quickly. If you use your youth as time to sow wild oats, you will reap the same in old age, and vice versa. “Men talk of killing time, while time quietly kills them” (Dion Boucicault).
