I personally am I strong believer in the need of having a personal side project. It can be something industry-changing or something as little as a small set of snippets you decided to open source.
Whatever it is, if you're spending personal time working on it, it's definitely something that merits attention, so share your passion in the comments, I'd love to know about it (and I'm sure others in this great community will too!).
Remember to have a great day!
