Did turning 40 rock your world?

It rocked mine.  It rocked mine so hard that my current life has almost no relation to the life I had just a little over a year ago.  Some of it was just life throwing curve balls.  Most of it is my complete and utter change of attitude about almost everything.  Not a change exactly, more like a coming back around to values and ideals that I always had but wasn't honoring.

Is this common?  I know about the cliched mid-life crisis.  The stereo type of which is a middle aged man buying a sports car.  This is woefully simplistic.  Not very helpful if you find yourself in an existential melt down.  It's something that is perceived as a weakness I think.  Snickered about behind your back.  Very unfair.  I think it's important to take stock in where we have come from and where we are going.  Look around your life's landscape and pull the overgrown weeds.  Add some new landscaping.  Plant a tree or two.  Change.

Is it good enough to live as you have always done, going through your days in a routine?  Sure, if that's what makes you happy.  But if you are reaching this crucial age, and you don't like how you're living than I say go for it.  Change your life.  Buy a sports car,  learn to parasail, lose a hundred pounds.  Life isn't over.  It's just beginning.  I promise I won't laugh at you behind your back.  I'm cheering for you on the side-lines.  I'm hoping that all of your dreams for your life come true.  Don't give up, its never too late.
I'm working it.  Trying to live my life the way I always thought I would. Are you?
