He who hath no ill fortune, is dazed with good.

Understand the thought

Meaning in plain English

A run of favourable outcomes can leave someone dazzled and less alert to limits. The saying questions judgment formed only under easy circumstances.

What the words are saying

Good fortune is pictured as something that can overwhelm clear sight. Someone whose plans have always worked may underestimate difficulties faced by others or assume that success is entirely their own doing. The saying can encourage humility and checking assumptions before the next decision. It does not require hardship as a lesson or prove that fortunate people are careless. The useful focus is whether earlier ease has hidden a relevant risk or source of support.

Everyday example

A team whose launches have gone smoothly checks its contingency plans instead of assuming the next launch cannot encounter trouble.

When to use it

Use it to question overconfidence supported mainly by an unbroken run of success.
