Not a superpower. Thinking all moments of every single day, although exhausting, does make one significantly more experienced with thinking and how their mind works than those who can choose not to think most of the time though if untempered these thoughts are typically nonsense. It’s an advantage in many situations to be able to think at light speed while everyone else is panicking, but the burnout that comes from not being able to ever turn it off is pretty nasty. It’s different with different advantages and disadvantages. I personally wouldn’t change my mind to be different, but I wouldn’t recommend a mind like mine to someone who wouldn’t be able to handle it since I’m barely able to handle it myself with decades of experience.
One thing I’ve learned about ADHD is that since we can’t control our thinking, we are each so divergent from the typical experience that we have little in common even with one another aside from common symptoms and the obvious reaction to those symptoms. My experience is not at all to invalidate anyone else’s experience. That being said, it’s very likely that the reason you are with your wife is at least partly due to how she is, and how she is is heavily influenced by her adhd. There are likely things you love about your wife that are directly influenced by her adhd or her life experience living with adhd.
