I was wondering if y'all have any tips on a strong opening sentence

So, I write essays a lot, and while I think overall I'm a good writer, I feel like the weakest part of my writing is the opening sentence.

I usually just go with a question meant to make the audience think, in theory I do this to help them become more engaged with content right off the bat, for example "Do you ever wonder about ______? Well here's why ____". But I learned this technique in like grade 5 so I'm not sure it's the best, and people have told me I should work on making my openings more effective. Anyone wanna share their techniques?
