I saw someone recommend this techno lent idea a few years ago that I really liked: **give up Color for lent. **

You might not be able to completely give up screens or the Internet. You might not even be able to give up social media. But one thing you can probably give up is Color. All mainstream OSes have a "grayscale" option. It's typically for color blind people and found under your OS's accessibility settings. But if you turn it on, you'll find that your brain gets a far lower dopamine hit when looking at a grayscale screen than a full bright color screen. Nevertheless, the features you actually need will still mostly work just fine.
