Excerpt from Hamlet, Act 3, Scene 2

I know that’s what you think now, but people change their minds. Often our intentions are strong at first, but as time goes on they weaken, just like an apple sticks to the tree when it is unripe but falls to the ground once it ripens. The promises we make to ourselves in emotional moments lose their power once the emotion passes. Great grief and joy may rouse us to action, but when the grief or joy have passed, we’re no longer motivated to act. Joy turns to grief in the blink of an eye, and grief becomes joy just as quickly. This world is not made for either one to last long in, and it’s no surprise that even our loves change along with our luck. It’s still a mystery to be solved whether luck controls love, or love controls luck. When a great man has a run of bad luck, watch how followers desert him, and when a poor man advances to an important position, he makes friends with the people he used to hate. Love is unreliable. A person with lots of money will always have friends, while one fallen on hard times makes an enemy of any friend he turns to for money. But back to my original point—what we want and what we get are always at odds. We can have our little dreams, but the fates decide our futures.
