I’d either advise a small break where you just focus on other hobbies for a few and let yourself relax,

or I would say learn something new like a new programming language, or a new area of programming (like game development or web development) and just try to make your own projects and stuff that you find fun or new,

or maybe focus on something different in tech, like try IT, Networking, Security, etc.

I suppose it would depend on the person/circumstance.
