I don't gatekeep.
Habitica
I have this as an app on my phone. It gamifies habits, chores and to-dos. It sounds silly, but it really has gotten me to regularly do those things I know I should do but can easily ignore (daily stretches, oil changes, reading, personal projects, blog post writing…)
I've also started to use it as a personal task-tracker. I've played with using Trello in the past, and while I'm not quite ready to give it up completely just yet, Habitica does seem more effective at getting me to actually do things.
Send Web Pages to Kindle
Amazon has an official "Send to Kindle" browser plugin (Chrome) that allows you to send any web page to your Kindle. I find this useful for certain long blogs or news articles I come across during the day but don't have time to read at that moment. In the past, those articles would end up in a tab in a Chrome session somewhere and usually forgotten about and shamefully closed a few weeks (or months) later. Since adding a daily 'read on Kindle' task using Habitica, having the option to just send these articles to another device for a dedicated 'later' time has been handy and convenient.
Bubbletea TUI
Bubbletea is a Go-based "terminal UI" that makes creating and using terminal apps a real joy. I'll create a dedicated post on my findings in the future, but it's such a neat framework.
Terminalizer
Turns your terminal into a GIF. Handy for quick demos, show-and-tells, and for jazzing up your README. While playing around with Bubbletea, I noticed a lot of demo GIFs in their READMEs and it was so nice. As a visual learner, I find these short little GIFs communicate so much more information than a paragraph or two.
It's easy to use. After installation:
% terminalizer record demo
% # Run your demo
% # ctrl+d out of demo
% terminalizer render demo
