Our lodge was built in the early '30s, so there is always something to be done around here. We could never afford to hire people to come in and do all of the repair work, so I get to do most of it, and Juanita gets to do most of the bookkeeping. I think I got the best part of that deal. I am NOT an accountant. I am a technician. It makes me happy to fix broken stuff.
I have worked as a "tech" my whole adult life, and learned a few rules that make the job easier...
Try to work alone. An audience is rarely any help.
If what you've done is stupid, but it worked, then it wasn't stupid.
Work in the kitchen whenever you can...many fine tools are there, its warm and dry, and you are close to the refrigerator.
If you can't find a screwdriver, use a knife. If you break off the tip, it's an improved screwdriver.
If it's electronic, get a new one...or consult a twelve year old.
Learn the terminology. It's like magic. People think you know what you are doing if you know the words.
Keep it simple. Plug it in. Get a new battery. Replace the bulb or fuse. See if the tank is empty. Try turning the switch on. Or just paint over it.
Always take credit for miracles. If you dropped the alarm clock while taking it apart and it suddenly starts working, you have healed it.
Regardless of what people say, kicking, pounding, and throwing sometimes DOES help. It's called "percussive maintenance".
If something looks level, it is level.
If at first you don't succeed, redefine success.
But most importantly, If it ain't broke, don't fix it.
