I feel the same. I not sure if I have ADHD, but I always have 2 mode of focusing on something, first one is shot burst of focus and other one is real locked in mode where I forgot to eat or drink water.
While second one is much better at delivering value it mostly activated on management/strategy games that I love :D
But with AI assisted coding now I can really work on my side project while having first focus mode. Im just writing or designing the parts I excited about, and then I let AI to handle boring task.
