So What, So What, So What??

I've been 19, 29, now 39...
At 19 I was pregnant.  My life seemed and was absolutly crazy.  I was so lost.  Little did I know my life was starting, really starting.
By 29 I had gotten divorced, met my soul mate, gotten married again, experienced loss, had a second child, made it through college,  and was pretty settled.
And now, by 39.  by 39.  by 39.
Not that big of a deal.
Really, it's not.
But just looking at those years between 19 and 29--seems like a lifetime of change took place in 10 short? years.
But what about after 29.
And up until now.
Well?
