How to avoid getting sick?

I’m about 2.5 years out and doing well overall. My only problem is I seem to get COVID more than others I know, despite trying to stay safe. In two years, I’ve gotten COVID twice and I’m worried about long term impact.

For those of you that have managed to stay safe from viral respiratory illness, how do you do it while still enjoying social life? I wash hands constantly. Always mask? Skip small group gatherings? I’m open to any ideas.
