Destruction of self confidence

[brewer]

"Don't be wise in your own eyes" or "Be little in your own eyes".

I think both of these are very good advice.

Very few people are wise, and very few people are important, in the grand scheme of things. Thinking too highly of oneself is a trap that justifies all kinds of bad behavior. 

This is true for everyone, religious or not.

Um....., not exactly the ideas in the bible. They need to be considered in context. 

Don't be wise in your own eyes: Proverbs 3

Be little in your own eyes: 1 Samuel 15
