It really is and most of us realize by the time we are into our 40's that the important things in our lives aren't "things" at all. We begin to notice sunsets, the greeness of spring and how good the air smells after it rains. All that wasted on youth, we were too busy preening in our 20's to notice much! In our 30's we are raising kids... either changing diapers or at some stage of toilet training, it takes over who we are or who we thought we were. You don't really know yourself until you are well into your 40's.
Sometimes it's lifestyle, you just wake up one day and say, "This isn't working"...and you decide you are going to make changes for the better. Could be health related changes, changing jobs or even relationship adjustments. Whatever... you decide that you want more, better, and you go for it!
And the next thing you know, you're on the road to Happy. The road smooths out, the days are sunny and when you take the time to smell the roses...well, they even smell sweeter!
Hope your day is filled with lots of surprises Derek... Happy Birthday!
