How do I organize my garage?
user
I’d start by sorting out all your belongings, then taking it one thing at a time.  First figure out what you need to take in order to use your garage as a workshop, and how to organize that work.  Then do the same for tools.  Then again with equipment, supplies, and any other belongings you’ve got.  Just sort them all by category.

I would consider finding some other space to store stuff you don’t need frequently, like books or old clothes, in the long run.
