Get a few non-WCA puzzles. Even just bigger cubes or bigger minxes. Things that you can focus on when you're not trying to enhance speed. Use these puzzles as casual solves, kinda meditative solving moments. Who knows, maybe you'll find a new love like I did and speedsolving isn't for you? I'm always looking for the crazy new puzzle to figure out, I really don't care how fast I can solve stuff anymore. I'm just saying, expand a bit past the WCA, find something unique, use the techniques that you already know. Figuring out a new puzzle on your own can be a great way to re-light your puzzle solving fire.
