The tide is at the flood for you now, and it will not wait. Step in while the water is high, because the same choice made late will run aground in the shallows.
William Shakespeare
Julius Caesar, Act 4, Scene 3 (Brutus)
There is a tide in the affairs of men,Which, taken at the flood, leads on to fortune;Omitted, all the voyage of their lifeIs bound in shallows and in miseries.William Shakespeare · Julius Caesar, Act 4, Scene 3 (Brutus)
