Julius Caesar

I know this isn't mine, it's from Julius Caesar by William Shakespeare but i love it, it has such meaning.

There is a tide in the affairs of men,

Which, taken at the flood leads on to fortune,

But omitted and the voyage of their life,

Is bound in shallows and miseries,

On such a full sea we are now afloat,

And we must take the current when it serves,

Or lose the ventures before us.
