I would also suggest making a game, especially if you're a more creative/visual-type person. What I found really fun was downloading some free or low-price pixel art packs and just dropping them in Unity, having fun making scenes with them, and then coding a small game around them. It's good chill times.

An example could be like…. making a browser extension to highlight some text and having ChatGPT spit out a re-phrasing of that text. Or whatever you wanna do.
