This piece comes from a quote from a professor of mine that said "Ideas are free, so we should have plenty of them." I took it to heart. I have a running list of ideas, ever-growing, waiting to be screwed in and developed. But even then, some ideas aren't worth your time and it's ok to let them die.
I encourage you to embrace the life and death of an idea. Hold onto the freedom that comes from the creation of new ideas, giving you the agency to choose what you want to focus on when it comes to these new concepts.

Sometimes that is just what an idea is, an idea. It doesn't have to be anything more than that if you don't want it to be. You can pick it up, test it, and then just throw it away without having to worry. You spend all of two seconds coming up with an idea. A simple thought, or flash of an image pops into your mind. You can help it flourish or you can let it go and move on to the next one.
I tend to overthink; I get an idea and it becomes larger than life before I even give myself a chance to test it. I put too much mental energy into the beginnings of something that doesn’t even exist yet, and I end up practically draining myself of all my creative juices before I even know if the idea is actually worth pursuing.
