The hard line between caring and loving your project/idea

I've often found myself falling in love with my projects and ideas at the beginning stage. What seems like a world-changing project can sometimes turn out to be a dud when you thoroughly break it down or validate it. Without proper validation, I would jump right into VSCode and start writing code, which leads to lost time and mental fatigue. There's a hard line between caring about and loving your project. When you love a project, you’re deeply passionate and emotionally invested, which can make it harder to move on when it fails. On the other hand, caring about a project means you're committed and responsible, but it’s easier to pivot or let go if things don't work out. How do you cope with moving on from a project you've loved versus one you simply cared about? Let’s discuss the emotional and practical differences in dealing with failed projects. What strategies have you found effective in transitioning away from a beloved project that didn’t pan out?
