Searching github by the “good first issue” tag can be a good way to get your feet wet on open-source contribution with small, often low-risk tasks that’ll get you used to the contrivution flow. Then, you can find a project you care about, find (and open) an issue with it, and make the improvement yourself! It doesn’t have to be big, a lot of small contributions add up quickly.
I missed the dodging and flurry-rush shrine in BoTW. Beat Ganon without ever learning. Finally went back much later and was like “wow, this game is so much easier now!”
