2) Most things shouldn't be taken so personally. I'm the queen of taking things personally. If someone makes an offhandedly rude remark toward me, I automatically assume I did something wrong and I'll stew over what it could have been for days. The truth is, sometimes people are in bad moods and they aren't being rude to you because of you, it's because of them. Because remember, nobody is thinking about you as much as you're thinking about you.
3) Always wear an underwire bra. I mean, you never know when you're going to be abducted, and the key to your survival/escape could be busting (hehe, punny) the underwire out of that bra and either picking a lock or stabbing your captor in the neck. When you write your memoirs about your abduction feel free to thank me for giving you the key to your escape.
4) Just because "it could be worse" doesn't mean it's not bad right now. In my experience, saying "Oh, it could always be worse!" when a friend is going through a hard time isn't helpful or comforting. I know I never like hearing it, because it makes me feel ungrateful and then I end up just feeling worse for being so selfish. The phrase. "it could always be worse" minimizes your pain/struggle, and what's helpful about that? Nothing. Sure, it could be worse, it could always be worse, but just because it could be worse doesn't mean you don't have the right to be upset for the struggle you're in at the moment.
5) It's easy to be negative, but it's better to be positive. There will always be things to complain about. No matter how rich, successful, popular, or blessed you are, you will always be able to find things to complain about, because life isn't perfect. But at the same time, no matter how bad things get there is always always always something to be thankful for. Don't lose sight of your blessings in the midst of a rough time.
