You'll never have enough shelf space, so don't buy any book you could get at the library. Why spend the money? Are you really going to read that book again? Sure, you could give it to someone else to read, but the library does that for you. (A good reference book, on the other hand, is totally worth buying.)
Old, unwearable socks make great dusting rags.
When I was five or six years old, I asked my mom, "What's a Democrat and what's a Republican?" After a brief explanation of what a political party is, she said, "Republicans usually care more about things like money and Democrats usually care more about taking care of other people." I thought about it for a moment and said, "Well, I think it's more important to take care of other people." She smiled and said, "Oh, that's what I think, too!"
If you get bored sitting in a waiting room and you don't have anything to read, look at signs around you and anagram the words into other words.
When making deviled eggs, don't get stressed out if you tear one of the hard boiled egg whites and can't use it. You'll just end up with extra yolk filling and that's the best part of it anyway.
Forbidding your child from watching TV shows like "The Dukes of Hazzard" and "Three's Company" will make those programs seem really attractive, and he or she may sneak over to a friend's house to watch. But when that child grows up, they will eventually realize that you banned those shows because they were stupid.
When traveling, pack light. If you're flying, stick to just a carry-on bag. Who cares if you wear the same things over and over? Either you're visiting friends (who shouldn't mind) or you're seeing people you'll never see again.
Avoid buying clothing that says "Dry Clean Only".
It isn't fair to dislike a group of people because of the way they look, what they believe, or how they live, as long as they aren't hurting anyone.
Yes, childbirth is painful, but it's what your body wants to do. When you're ready, you're ready. And during pregnancy, when the baby reaches up under your ribs, it doesn't hurt. It's just sort of... awkward.
If you smile a lot and you're a really good talker, you can brighten the grumpiest customer service worker's day, even the surly, underpaid grocery store cashier. I'm more of a "make the interaction brief and polite", path-of-least-resistance kind of gal, but engaging in friendly banter with everyone is my mom's default. And I have to believe her success rate - measured by the number of people who reciprocate with a sunny response - is in the ninetieth percentile. I'm just glad there are a few people like her in this world, to help make up for all the jerks and the self-absorbed cell-phone talkers and the introverts (like me).
