We all go through hurdles in life. There are moments when you think something couldn't get worse and it'll never be better. There are times when you think you're alone and nobody can cure the emptiness you feel. In those times, faith is an important medicine.
Believing in something higher won't do much for those who don't truly understand that what they feel matters. Good vibes produce good energy. If you ever wonder why nothing is going your way, it's because you're thinking that it won't... You've lost the race before you've even spotted the finish the line.
Perception is an important factor of faith. How you want to be perceived and what you see is what you'll become. The key to this all though is believing. You've got to.
