Absolvement of your sins, seeking forgivness from God.
Since we are talking about God and eternity (as opposed to our lifespans, which are not eternal), we are talking about a religion of some kind. In some faiths that believe in a God, and in souls, and in our punishment or reward (or redemption) after our bodies die, the eternal separation of our souls (which are believed to be immortal) from the presence of God is considered the worst punishment in Hell. The underlying belief is that our souls naturally yearn for what is good and so they yearn to be in the presence of God. Whether the reader believes this or not is a matter of personal faith, and there is no justification here for insulting people who do, or do not, believe it.
Performing works of mercy helps us grow in love, compassion, and selflessness, which are traits essential for eternal life in communion with God. By caring for others and showing mercy, we imitate Christ's example and align ourselves with His teachings, increasing our readiness for the kingdom of heaven.

Eternal life is a concept that is often associated with religious beliefs and does not have a proven scientific basis. The security of eternal life would depend on one's faith in the relevant religious teachings or beliefs. From a scientific perspective, achieving eternal life is not currently possible.

Tartarus
I don't know the author's name, but I remember my younger brother memorizing it in elementary school as: Excuses, excuses, excuses! Excuses are tools of incompetence that build monuments of nothingness. Those who specialize in them, accomplish nothing at all, but excuses, excuses, excuses. Not as the first responder suggests here: "Excuses are monuments of nothingness, They build bridges to nowhere, Those of us who us these tools of incompetence, Seldom become anything but nothing at all."
