I can't stop thinking about it
Search for the ideas you can’t get out of your head. If there’s something you can’t stop thinking about, pay careful attention.
If it truly won’t let go, you should find a way to do it. Your subconscious is trying to tell you something.
Even if it doesn’t work out the way you’d hoped, it’s better to have made a mistake trying something than to make the mistake of convincing yourself you shouldn’t try.
