Ojú ní alákàn fi ń ṣọ́ orí.

(The crab watches after its head with its eyes.)

Eternal vigilance is the price of liberty. This proverb focuses on using what you have to protect what matters most. When you are limited in a particular situation, make the most of your available resources to defend your most vulnerable or valuable point. Wisdom is matching your defense and effort to your real resources, not getting paralyzed by what you lack.
