Fear is a powerful emotion. It's a powerful enemy and can be a powerful ally. It causes people to do things, and it also causes them to back down from doing things. Sometimes both causes can lead to good effects, and both can lead to bad ones. Master the power of fear, and harness it. Ironically enough, do not fear- fear. Even though Roosevelt famously said "The only thing to fear, is fear itself." If you don't embrace it at times, you'll never discover what a powerful ally it can be.
And on that note, I unleash upon the world a poem that I had written during my creative writing class a few semesters back. I won't claim this to be my best works, though I do believe it holds a special place in my heart. Enjoy.
