1) QUESTION: I'm curious what advice Helen Gurley Brown would have given her 21-year-old self, career or otherwise, now that's she's older. - Chacha
ANSWER: Good things will happen if you get up every day and work at it. It's a lot of trouble to do the best you can. It's the secret of my so-called success. A lot of concentration will bring results eventually. If you aren't getting any recognition after a while, then you probably aren't doing something you could be. Work harder.
2) QUESTION: What do you think of hooking up? - BookMama
ANSWER: I think it's OK—do it!
3) QUESTION: In a world where marriages fall apart, how can I make mine stick? - MISUNDERSTOOD
ANSWER: Treat your husband like a friend. Be reasonably honest, considerate and do things with him that he enjoys doing. Be a good person to him—that's a good recipe. Be polite, kind and be careful of your husband's feelings. And you both need to be responsible for each others' health, well-being and money!
ANSWER: Don't put up with a jerky man for too long. You need to let go and find someone who is more worthwhile. Being unhappy with a man is about as unhappy as you can get. And I know because we've all been in a situation where we're crazy about someone who is treating us badly. If you're having trouble, break it off—see a shrink. A professional person can help you see your way out of it.
ANSWER: It doesn't work: When someone isn't faithful to you, it creates jealousy and insecurity. And if you're getting married, it means you're going to devote yourself to someone—that's the point.
