Believe that tomorrow will be a better day
Believe that it will never fade away
Believe that your faith will never fray
Believe that in the end it will be okay
When you believe, all can come clear, because your heart will lead you to your desire. Believing is what your heart will tell you to do, but ultimately, you must do it yourself. And when the two come into place, the light will come. Of enlightenment, of joy, and of satisfaction. However, if you do not even believe, then it is hard to take actions, and you will only dwell in the dark, consumed by it. Only when you believe, does the first ray of light spill in, and show you the way through the doorway.
The most important thing: believe in yourself.
