Dunno about tidy home tidy mind? My sister is a neat freak and her home always looks like it belongs on the inside of one of those glossy magazines. She is into control........ mega control. I recon she is part OCD.
I tidy up every so often then things fall in a heap. Tidy Up and then fall in another heap. Maybe it is true..... lols. Moving house always helps to clean things out.
But I love the "Just keep swimming, just keep swimming". Turtles may be slow but they get there in the end. So will you.
