Is pride a strength or a weakness?

Pride? Or standards ?

Both. Everything in life usually falls best near the middle

An excess of pride is a deadly sin, isn’t it?

It can be both

I read pride as a defense mechanism..

then you have answered your question ,🤗

It depends on how you wield it. If you use it for your own self-satisfaction, feeling how good it feels to know your own purpose in life, I think that's a strength. If you use your pride to run over people, to make them wrong so you can be right, to think you're better than they are, I think that would be a weakness.

Pride is a tricky word:
It can mean anything from justly earned confidence, to pleasure in your children's accomplishments, to arrogance.

How exactly does pride ruin your relationships?

Strength!!

Mostly a weakness but dignity is a strength. Dignity in my case means I always work hard and try not to bother people too much or depend on them too much. But life does require interdependence in some ways.

Both

It depends if it's healthy or unhealthy pride, just like it depends if it's healthy or unhealthy shame.

Either can be a strength or a weakness.

I don’t have any. My parents were a mix of shy and humble.

Pride annoys me. Especially at work.

It can be either, actually.
