How do you transition from beginner OSS contributions to meaningful long-term contribution?

I’ve gotten a few PRs merged into the pypdf repo so far, mostly test-related changes and small fixes.

I understand that’s the normal entry point into OSS, but I’m trying to understand the long-term path now.

At what point does someone stop being “a contributor” and become genuinely valuable to a project?

Do experienced contributors usually:

• stick deeply to one repo?
• contribute broadly across many projects?
• follow trending ecosystems?
• or build expertise around a specific domain/problem?

Would like to hear how people here approached it after the beginner phase.
