I'm Lesley I knew I had ADHD at 19. I wasn't diagnosed until I was 40. Somewhere in between I worked out that the most overstimulating thing in my life wasn't noise or people, it was clutter.
Before any of this I ran rooms full of young children, where everything has a place, everything is safe, and the whole space is set up so every kid in it can succeed. I've run my own home that way ever since. Yours should be no different.
I built The Chaos Coordinator because knowing how to declutter was never the hard part. Starting was.
