This is a mutual experience that many people can relate to but its mechanics is also core Adhd where this scenario is more extrme and frequent. (Possibly even with important life choices and not just hobbies)
Normalize acknowledging the smaller neurodivergent features that exists in most people as it can help them understand major ones. but do keep it distinct from “everyone has a bit of adhd/autism/anxiety” which is tonedeaf
I have a really nice set of whittling knives from the time i was passionately experimenting with a borrowed knife.
Guess how much time i have whittled since acquiring that set?
In my defense apparently i missed out on a free tiny whetstone because i bought on a local farmers market rather the amazon page. From this i have convinced myself i need to master knife sharpening and maintenance skills first so i don't abuse my set.
So the fine edge of the blade can warp as you use it. The honing rod helps straighten that back out to improve cutting. The whetstone actually removes bits of steel in order to create a new edge. Honing should be done regularly, but using a whetstone to sharpen the blade is periodic.
Aaaalmost happened to me, unti one I day I thought about putting inside a cup of milk, a banana, 1-2table spoons of greek yogurt and a vanilla icecream protein poweder scoop (from ON if it matters). I made my blender useful again and found a simple and quick breakfast :)
