I believe my journey through life has been more like a mine field than a beach ball. After reading your hub on your own life I can surely see where yours is much more like the ball.
Mine has been a more controlled flow where I set my goals and work towards a reasonably satisfactory ending only to step on a mine and find the whole thing blow up in my face. Mine is a world of extremes where things are either really good or very, very bad. Very cut and dry, little meandering like the beach ball or a lazy river. More like buffalo grazing quietly until hunters come and drive me from the cliff.
As I answer your question I realize my outlook may seem somewhat morose, however I have few complaints. Good or ill, my life has been a most excellent adventure, to coin a phrase from ole Bill and Ted. I guess it is the variety in how lives flow that keep them interesting, be they beach balls or mine fields. Bottom line is, with out good there can be no bad and without a little, or a lot of bad in out lives how can we possibly appreciate the good to the fullest.
