Hall of Infinite Doors
"I would never have the patience to finish this puzzle in the real world, even if I did have the free time. This place is different though, there is nothing stopping you from focusing. You can even tune out the sounds of your own body if you wish. Time is different to, I can spend the equivalent of days in the real world with intense focus and barely notice the time passing at all. This five thousand piece puzzle is known for its difficulty, but I know I'll finish it. There is no rush, no hurry. It's so peaceful. I will probably return to the real world when I finish to live a bit more of real life, but when things get tough or I need a break, I can just find a puzzle, bring it here and find a little niche where I can work in peace and quiet. It's quite wonderful really."
