You'll never figure it out no matter what you do.
You will not live forever regardless of how you live your life.

You will never "get ahead" in man's (the human) world. Too many people, too many
factors, too many places so what exactly do you think you are going to get ahead of?

When the goal is set you want it. After you accomplish your goal you don't want it,
forget about it or take it for granted.
Or it disappears through theft, becomes worn out due to its use and age, is outdated or dies.

Material things end up in thrift stores, landfills or graves and eventually disintegrate or dissipate.
