"Shakespeare" says that "There is a tide in the affairs of men, which taken at the flood leads on to fortune."
Is it a coincidence that Francis Bacon in his essay "Of Delays", expresses exactly the same thought but in different words, when we read
"Fortune is like the market, where many times, if you can stay a little, the price will fall," and "Occasion turneth a bald noodle after she has presented her locks in front-- and no hold taken"
--that is to say, if one does not grip occasion at once the opportunity will not arise again.
