I have no doubt that to learn this off by heart would greatly benefit anybody.

Act 4 Scene 3

BRUTUS
Under your pardon. You must note beside,
That we have tried the utmost of our friends,
Our legions are brim-full, our cause is ripe.
The enemy increaseth every day.
We, at the height, are ready to decline.
There is a tide in the affairs of men,
Which, taken at the flood, leads on to fortune;
Omitted, all the voyage of their life
Is bound in shallows and in miseries.
On such a full sea are we now afloat,
And we must take the current when it serves
Or lose our ventures.

Shakespeare
