keep any jars for nuts and bolts. The giant pretzel jars are the best.

1/4" BBs make for great plugs for vac lines. Zip tie your vac lines on(very important in boosted applications)

buy CHEAP tools from the dollar store and harbor freight and leave them everywhere. its nice always having tools and not having to run around to find tools or leaving them somewhere. Keep the nice tools in the garage.

I collect rainwater from the garage into a 55 gal container. I wouldn't recommend it for drinking, but its great for washing your hands with if you dont have a water line in your garage.

speaking of water, filter the water in your house, you wouldn't believe the stuff those filters grab. Your tap water will be as good(if not better than) as store bought.
