I'm currently busy these days (became a tech lead/engineering manager hybrid), but if I want to work on open source, I just go ahead and get involved - read the READMEs, CONTRIBUTING.md, peruse the issues, debug the reported issues...and come back with findings, opinions, or sometimes a PR or few. There is no shame in not contributing to open source - most developers don't do much beyond using it. There is also no shame in failing to bring new insight. I would say that make sure that it is something you enjoy doing, because otherwise it will tax your mind some to force yourself to make the effort.
