We need to know life is short and heaven is eternal.
Furthermore, we can't take anything with us at the end of this life.
People try to enjoy more material abundance, but in the end it is just futile.

Therefore, we need to invest our lives in something worthwhile that will last forever.
That is to follow God's teachings and prepare for heaven,

and I'm sure there will never be any regrets about the consequences.

[Psalm 90:9–10]
All our days pass away under your wrath; we finish our years with a moan.
Our days may come to seventy years, or eighty, if our strength endures;
yet the best of them are but trouble and sorrow, for they quickly pass, and we fly away.

[1 Peter 1:24–25]
For, “All people are like grass, and all their glory is like the flowers of the field;
the grass withers and the flowers fall, but the word of the Lord endures forever.” . . .
