Not sure if it’s flylady.com or .net. I have lost some ground but never all that I gained. It took a couple of months. One room had been the catch-all junk room for YEARS, my daughter and I committed 15 minutes a night, were ruthless with ourselves and the stuff and in a week it was a habitable guest room. Last summer did the same for our garage, I renovate houses and after each job all the tools, leftover supplies etc. got piled in the garage – it was ugly. That took more like three days, 4-5 hours a day but it was a real priority for me and I was between houses.
