I think you're worrying too much. Sounds pretty normal to me. Try to keep learning, practice coding problems if you're so inclined or get a hobby. Get out more. Spend more time with your family. Teach a few courses if thats possible. In this context, I don't think there is any such thing as linear improvement.

Retire, relax, enjoy your family. It is just a phone. Not worth it.
