If you don't want to suffer in old age.

1. Don't depend on anyone. Dependence forces you to destroy your dignity.
2. Don't give everything away. If you empty yourself now, no one will replenish you.
3. Let go of unnecessary burdens. Release resentment, old wounds, and bitterness. Walk away.
4. Distance yourself from those who use you. Old age doesn't hurt because you are alone. It hurts because you are surrounded by the wrong people.
