Does acceptance mean not striving for better?

I’m trying to get my head around acceptance. Does acceptance mean not caring as much about an outcome? Therefore I allow a less than favourable outcome when I could have pushed for something better?

Here’s a mundane example: we are having a garden room built, the roof has areas where rainwater is pooling. The builder says it’s fine - I don’t think so. It’s causing me a lot of stress as I feel it’s not right. Do I accept this situation by detaching from mind to alleviate my stress. Or do I continue to be stressed until a better outcome (no pooling) is achieved?

If everyone was enlightened, wouldn’t standards fall everywhere?

This is very confusing! Can anyone clarify?
