You mean like getting distracted while actively having sex by the way the light is filtering through the leaves outside my bedroom window?
How about missing half of what your spouse is saying to you because you suddenly remembered an insight you had about how relative speed and the perception of the passage of time are linked, thereby forming a universal constant connecting both?
… or maybe you mean not being able to remember anything you need while at the grocery store because instead you remembered you needed something from the auto parts store, and having to drive to the auto parts store and buy that thing because it completely fills your consciousness and makes you unable to think about what food you need for the week until you have it in your hand?
In all seriousness - whether an activity is “dull” or not has little bearing on whether I can focus on it. My focus is ephemeral, and feels like something completely out of my control most of the time. Medication gives me some ability to direct it.
I hear people talking about “not looking forward” to doing things. I can’t relate at all. I dread even the things I want to do, because I’m not sure if I’ll be able to do them.
It all lies on a spectrum. No one likes doing something dull but with ADD it can become so intense as to be debilitating. You always procrastinate to the last second on everything, sometimes far past the last second. Left untreated you attain a reputation as a lazy flake and it affects your work, your relationships, etc.
Yes, and no. Yes, because people do get bored. No, because with ADHD, you can’t even force yourself to focus despite the boredom. Bribes, identification of potential consequences, punishment - none of these work.
This doesn't sound like a mental illness, but rather a part of the human condition, don't you think?
