I find the key to getting into my garage is to think it out. Don't get into a rush just because you have the building up, but think about all the shelf space and cabinets, etc. to accommodate storing all the items you will have in there. With no shelves, everything has to go on the floor, and that eats up all your space. Keep as much stuff off the floor as you can, put as much equipment on wheels as you can, and don't start ripping your truck apart until you have the inside of the shop finished too. Keep you vehicles out of the way of building/finishing your shop. Otherwise, you are just moving your stuff from one spot to another. It's enough work to do it once and with that stuff out of the way.
