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.
William Shakespeare

The sea, once it casts its spell, holds one in its net of wonder forever.
Jacques Yves Cousteau

The sea speaks a language polite people never repeat. It is a colossal scavenger slang and has no respect.
Carl Sandburg

The sea, the great unifier, is man's only hope. Now, as never before, the old phrase has a literal meaning: we are all in the same boat.
Jacques Yves Cousteau

Even Castles made of sand, fall into the sea, eventually.
Jimi Hendrix

From too much love of living,
From hope and fear set free,
We thank with brief thanksgiving
Whatever gods may be
That no life lives for ever;
That dead men rise up never;
That even the weariest river
Winds somewhere safe to sea.
Algernon Charles Swinburne
