1. If you're not being appreciated (either at work, in friendship or relationships) DO something about it. Sometimes you are so sure that you are going to be recognized for all the hard work you're putting into something, and then poof! no one recognizes it. Don't complain, just do something.
2. Kind of on a related note, don't compare your accomplishments or what you deserve based on what other people get. You should compare against yourself and the work you put into something, not really against what other people are doing. Just worry about yourself, silly!
3. Sometimes pizza can be your best friend. Don't argue with me on this one.
4. Washing your hair right this minute isn't as important as cuddling with your puppy for a few hours. After all, he will love you dirty hair or not!
