We need not be afraid of expecting the unexpected, but let us wheedle each instant we enjoy and endear each happy moment we encounter; let us watch each step we take and each move we make, ever since happiness is a loving and appealing fairy, but utterly frail and vulnerable. (Happy days are back again)
Better to step out of your comfort zone, enjoy new experiences & not know what's coming your way, than stick to routines & be bored with the same end results.
The unexpected will occur, but in the end, your life will never seize to become what you continuously make of it.
I'm not absolutely certain of my facts, but I rather fancy it's Shakespeare -- or, if not, it's some equally brainy lad -- who says that it's always just when a chappie is feeling particularly top-hole, and more than usually braced with things in general that Fate sneaks up behind him with a bit of lead piping.
