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.

There is no doubt that Shakespeare was a great poet. I recently bought an Agatha Christie novel which seems to be inspired by that poem. And now I‘m thinking about the tide.
