Don't put all your eggs into one basket.

Depending on a single plan, investment, or opportunity leaves you vulnerable: if it fails, you may lose everything you committed to it.

The proverb recommends spreading what matters across several options, so that one setback does not undo all your efforts or resources.

Use it when advising someone not to stake all their money, time, or hopes on one outcome. It fits decisions where having a workable alternative could lessen the harm of failure.
