As someone diagnosed with ADHD, I can easily sit quietly in a room with my own thoughts for 20+ minutes.

What I can’t seem to do is make the two simple phone calls I need to make and write the one page report that I need to write before the end of the week. That’s literally all I need to do today, I’ve been at my desk for two hours and have done none of it. If I got that done now, I could coast the rest of my work day but instead I’m going to sit here and stress for a few more hours before I finally do any of it. Why? I can’t tell you because I don’t know.
