tealin | Taking Leave

We defy augury. There’s a special providence in the fall of a sparrow. If it be now, ’tis not to come. If it be not to come, it will be now. If it be not now, yet it will come — the readiness is all. Since no man knows of aught he leaves, what is ’t to leave betimes? Let be.
– Hamlet, Act 5 sc. 2

There are a lot of quotable quotes from Hamlet, to the point where we quote them all the time without knowing where they're from, but I'm surprised this one doesn't get more play.
