TRAIN your mind to see the good in every situation. It won't come naturally, you WILL have to work at it, but eventually it will become second nature and you will have joy in your life even when things aren't going your way.
Your heart knows things that your mind can't explain. And that's why I can't keep a relationship. My mind can't put into words what my heart is feeling. So I'm quiet! I just don't know how to let it out.
