I agree. In my case I am physically very fit but sometimes neglect my health in other ways, including mentally and definitely including poor sleep habits.

Regarding what you said about focus, I think an ADHD diagnosis might help a lot of people here. I suggest asking for a full profile including WAIS testing, which assesses intelligence, because it is the "deficit" between various types of intelligence and attention that matters. Highly intelligent people sometimes are overlooked because their focus, working memory, etc. seem normal or even better than average, but the gap between those and their intellectual capacity creates a lot friction at least for some people.

I recently got diagnosed and am really looking forward to taking a low dose of stimulants in the mornings on work days, I hope it will help me "find a clear path" in my professional life.
