I'm always game for cleaning & organizing. Big on containers. Especially milk crates I used to nab (with permission) from painting Boys & Girls clubs. For example, 1 crate is dedicated for drywall finishing tools, another for tile , another for caulk.. just grab and go.
At the risk of sounding like some weirdo, I hung a ton of old kitchen cabinets in the garage. Each one dedicated to something. Cuts down on clutter.
