Recently, what have been working for me is to take a day off just to explore stuff that interests me related to programming. I've been learning sleep states and working on the Rust track on Exercism.

The productivity boost that you get from Claude Code should be reinvested into learning your subject area deeper, rather than just churning out more superficial code.

It makes me happier this way. Experiencing flow is the best way for me to feel happy, and programming was the most reliable way to achieve that before Claude Code / Codex.

Yeah, I think in order to become an actual senior developer you'll need to do actual coding and not only vibe coding. Otherwise you'll never get the full understanding of how things actually work.
