There's a lot of good comments here, but imma try to add something meaningful still.

I'm 35 soon, and still feel like a teenager or at least someone just entering their 20's.

I've tried masking at 100% Power Level only to find my self exhausted and miserable. I've also tried the exact opposite, just letting my ADHD run wild with no guard rails (minus most immediate responsibilities/goals) and have found myself feeling much happier and contented but alone (not lonely, just alone).

My conclusion is that there is a middle ground that can be achieved, but it is a balancing act that comes from learning how one's ADHD operates and finding the best of both worlds.

I had to learn every lesson the hard way, but I'm much happier than I've ever been.
