 Always approach life expecting the best, and don't let the world's negativity weigh you down. Never be afraid to stand out and be bold, you're going to change the world. Don't let anyone tell you otherwise.

 He's going to say he loves you until the day you die. You will always love him no matter what he says or puts you through. Never give up.

 Make your decisions for you, and only you. In the end, you need to do what is best for yourself, and that is the only way you'll be truly happy.

 Throw a few fits. Don't let crappy people push you out. I'm not saying lose sight of who you are, but don't let jerks push you into that box you know you need to break out of.

 Those many years of being single, and feeling like you aren't doing anything with your life, are going to be completely washed away. When you meet him, he'll tell you the plan, and you will jump at the opportunity. And it will be totally worth it. You won't believe where we end up.
