When is it time to step down from a project?

I started coding when I was 12, and over time I’ve built tens of apps, websites and programs. Most of them didn’t have a clear purpose so I ended up leaving them unattended. However, I do remember one particular project I created during the pandemic: an augmented reality app. I worked on the project for around three years and last summer, while talking to some friends and my mum, I ended up deciding to terminate the project. Have you ever been in this type of situation where you are afraid of stepping down from a project because you’re perhaps emotionally attached to it?
