How to help yourself?

Did you ever have the experience going back into a project you have not touched for 6 months -- why did I make this change?

Or did you ever struggle to get all the dependencies installed to build a project you wrote?

Or did you ever wonder -- will this change break something I'm not thinking of?

Or did you ever question -- how do we actually deploy this now that it is updated?

Ironically, when you try really hard to help others use your work -- documentation, tests, CI/CD -- you are mostly helping your future self.
