Old stuff from my real journal
Be yourself. There is no one else for you to be. Don't spend time trying to be someone who you are not, especially to impress someone or to fit in. It just isn't worth it. Your will be much happier being around people who like you for who you are naturally.
Enjoy who you are. Because really, you're stuck with you for the rest of your life. Don't waste it hating yourself; find joy in who you are, and embrace the things you like about yourself rather than picking out the things you don't.
Embellish everything you do, just a little bit. Put a little swagger in your step as you walk down the hall, or flourish open a door as you enter the room. It will make you fell like you are in a movie, or at least make some of the more mundane things in life far more enjoyable.
Be sincere. Say what you mean, and mean what you say. There is no point in leading people around with false information, especially if you are going to be upset later when they believe you. Just let the people who matter to you know what is on your mind, and things should just go much more smoothly in general. In order to live around any people in any setting, there must be honest communication, or else things are bound to go awry.
