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.

- Shakespeare in Julius Caesar.

We all fear uncertainties and the things we know too little of to control. The 'what if-s' or 'perhaps-es'. Rationalising our motivations, nominating values of chance and probability to the paths before us, hoping that just maybe. Just maybe, it'll be as simple as a math equation. That maybe I'd find the one right answer as with chem or bio or physics. But we'd never know would we? For all the hemming lets slip the flood; that, which we console ourselves with the pessimism of the things which could have been.
