For best programmer that might be to learn more Data Structures and Algorithms. Maybe try some LeetCode. See if you can find a senior programmer to be your mentor.

For best developer, I think it is good to learn a bit about each team member's role. Learn some UX design, Scrum Master, Tester, Product Owner and Database Admin. You don’t need to learn enough to be able to do their job but enough to understand how and what they work with.

Keep learning programming, more languages, you come from the web, learn some Golang, Rust, Elixir, Python, to learn different paradigms. Do some side projects about things that you are passionate about (I play Dungeons & Dragons so I have built tools and websites to help with that).

Maybe get a job at a consultancy, you get to work with different clients in different domains and learn a lot.

But as others have pointed out, don’t burn yourself out. It sucks and takes a long time to come back from. Godspeed
