Fall back to 75% or 50% every now and then and be conscious that it's not bad at all, but still progress.
I don't know where you are in your lifting career, but it pays 5x later on, when numbers don't matter anymore. You'll be amazed how quickly you can build strength back up after a break or injury or how much muscle is still "just there".
I don't think lifting weights would popularly fall into the category of being a wise thing to do, but I'm sticking to it. Conditioning your body is key to living your best life, and being healthy enough to help those around you live theirs.

You're not kidding. My most recent break was my longest, and I was dreading coming back to it. I felt like a hot sack of garbage, any exercise was awful, and I was soft as it gets. But maybe 2 months after I started up again, my lifts were not all that far from where I left them. I had no idea I had it in me. I guess I took almost 3 years off from any regular lifting (had a baby and life got away from me).
These days I don't really lift for anything other than strength and general well-being, though I started with a pretty explicit focus on building muscle, haha. I stick to a fairly basic 3x3 routine rotating a handful of compound lifts, then I've got a handful of calisthenics-based exercises I've come to really enjoy. Weighted pull ups, dips, push ups, some ring exercises, etc. I keep my reps low there too, usually between 5 and 10.
I really love 3x3 these days because I find I can go hard without overdoing it. I used to do a 5x5 routine and sometimes, shit, I just don't want the extra reps at all. I don't need them. I'm there to condition my body, not beat the hell out of myself. With 3x3 I'm arguably stronger than I've ever been, less muscular, and definitely less injured. I never got hurt too much, but those nagging pains and aches aren't as much of a thing anymore even though I'm older and shittier than ever. It's definitely an individual choice, though. Some people love the higher rep, lighter weight thing. I'm a slow, lazy, poorly motivated person who's pretty please if they just manage to show up.
