All of my PRs in 2018 are linting and warning shaped. By using these libraries, I experienced some of their unfinished edges first-hand.

Making an open source contribution has similar motivations to creating a startup: solve a problem you have in an environment you know. Sending a PR requires familiarity with the project; it requires you to have used the code. To send more PRs in 2019, I need to use more libraries, which means broadening scope and taking on projects in new domains.
