Once bitten, twice shy. Literally, if a person is bitten by a snake at some point (it is a painful experience), then in the next ten years, they may be afraid to see a well rope (a harmless object). This is because they associate the image of the snake with the well rope and extend the threat of the snake to all objects with similar shapes or textures.

This sentence is usually used to describe a person's psychological state after experiencing a pain or frustration. They may be too cautious because of a failure or injury, and may even avoid contact with similar situations completely. This mental state may hinder their growth and development, because they can't learn and grow from failure or frustration.

However, this sentence can also be interpreted as a warning to remind people not to be too afraid or worried when facing difficulties or setbacks. Although a failure or injury may be painful, it doesn't mean that they can't learn from it, or they can't try again and succeed.
