What are the aesthetic sentences that backfire?

The counterproductive aesthetic sentence is:

1, I tried very hard to save it, but I found it backfired.

I don't know how to express my apologies. I didn't mean to make you sad. I wanted to bring you happiness, but it backfired. I'm really sorry!

I don't know how to express my apologies. I didn't mean to hurt you. I wanted to bring you happiness, but it backfired. I'm really sorry!

In real life, we often think what is the best, but the result is the opposite, which makes us very unhappy. We should believe that whatever we have at present is the best arrangement for us, whether in good times or bad. If so, we can be grateful in prosperity and still be happy in adversity.

5. In the wear and tear of the annual rings, sadness and joy were precipitated, but a layer of unforgettable sadness floated, which I desperately forgot. In the end, it turned out to be counterproductive.
