I haven’t the foggiest idea what you speak of there, but I do know that staring at a problem too long alters your vision of the problem as a whole. Start your down time by completely disassociating yourself from the problem entirely. Do something completely uncharacteristic for you. Make it something which can fully absorb your attention, and something way out. Car surf, or go shopping dressed like little Bo Peep, or travel to a community you don’t frequent and find a place to participate in karaoke. Spend an afternoon volunteering to be entertainment at a daycare. I am guessing slides are cleaned well between uses. Do that with your focus. Cleanse it, and come in fresh. That is the very best I can offer you.
