If you say that you find it nigh-impossible because of how it interacts with your neurology, I believe you. (Not arguing--it's just a possibility you didn't include.)I guess being a Dungeon Master is a hard as you make it. If you say it's super- hard, expensive, and time consuming, and it feels like a thankless job, I believe you. If you say it's deeply rewarding and feels like time and money well-spent, and that the smiles on your friends' faces make it all worthwhile, I believe you too.
