If a person has no long-term worries, he must have immediate worries

Look far ahead

Think twice before acting

It is better to retreat and build a net if you are envious of fish in the abyss. "It is better to raise the soup to stop it from boiling than to draw fuel from the bottom of the cauldron."

Be prepared for danger when you are in peace. Blessings depend on misfortunes, and misfortunes depend on blessings! It is a blessing in disguise, and knowledge of safety is not a blessing.

Look forward when walking and think backward when doing things
