1. If you can't find a screwdriver, use a knife. If you break off the tip, it's an improved screwdriver.
2. Try to work alone. An audience is rarely any help.
3. Above all, if what you've done is stupid, but it works, then it isn't stupid.
4. Work in the kitchen whenever you can... many fine tools are there, its warm and dry, and you are close to the refrigerator.
