I was diagnosed in my 30s. In retrospect, it explains a lot of difficulties I have had for my entire life. I wasn't hyperactive, so they mostly went unnoticed by other people -- it's really hard to know whether your struggles are unusual or not from the vantage point of your own head. I would say that if you feel good and life is working for you, then you don't need to do anything. If your life circumstances change (e.g., for me, our having a child definitely exhausted my ability to grit my teeth and push through my focus issues with all nighters, followed by sleeping all day to recover) then help is generally not far away!
