Wishing Ring

There are tons of fables, fairy tales, and stories about being granted wishes. Almost all of them involve finding a ring, or catching a fish, or rubbing a magic genie lamp that results in you getting three wishes. The first two are usually ill-advised and you need to use the last one to undo the effects of the first two.
   That seems like a lot of wasted effort just to learn a lesson about morality or greed or lust that you probably should already have learned.
   So I got to thinking, what would good wishes be? I'm talking about ones that wouldn't ironically backfire on you or wink you out of existence.

*Fix the air conditioning in my building. Of course, that would probably make it like the South Pole in here, and I don't like penguins. They're not trustworthy.

*Bring prices down in Whole Foods. Of course you can't use wishes to make impossible things happen, like touching your right hand to your right elbow, so this would probably just be a wasted wish.

*Make it so my shirts would never need to be ironed. Which would probably turn them into polyester.

*I'd never want to go hungry. Which would probably turn me into a tree or something else photosynthetic, like phytoplankton.

*Give me the power to run really fast, like the Flash. But I'd probably run right out of my clothes, which would be freeing but would ultimately be embarrassing.

*Find out the secrets to everyday things that no one seems to know the answer to. Like what fire is, exactly. Can't think of a way this would backfire... except I'd probably have to become one of those mountaintop monks, dispensing wisdom only to those with enough moral fiber to make it all the way to my cave. Which ain't bad, actually, as long as I had really fast wireless.
