This one provokes thought...

Destiny, I feel, is also a relationship - a play between divine grace and willful self-effort. Half of it you have no control over; half of it is absolutely in your hands, and your actions will show measurable consequence. Man is neither entirely a puppet of the Gods, nor is he entirely the captain of his own destiny; he's a little of both. We gallop through life like circus performers balancing on two speeding side by side horses - one foot is on the horse called fate, the other on the horse called free will. And the question you have to ask every day is - which horse is which? Which horse do I need to stop worrying about because it's not under my control, and which do I need to steer with concentrated effort?
