It is a great truth that not many people understand. Life is filled with many trials and adversity. There are many beasts and nightmares which block your path to happiness and peace, and when faced with such hardships many people feel the need to cry out for a hero, but the person who is in the best position to defend you is always you. Be your own hero, and save yourself; for heroic knights in shining armor only exist in fairytales.
On a side note, I hated to use the imagery of a knight slaying a dragon because of my affinity for dragons and my disdain for the so-called "chivalrous" knights of medieval Europe, but I felt it still appropriate imagery since many people equate the symbolism for heroism with this iconic mythological scene...despite how rubbish it is.
