I'm genetically-predisposed to being a pretty grumpy mf'er. I remember being bored out of my skull and miserable through most of my adolescence and early adulthood. Not that I'm recommending anything but, I haven't been bored ONCE since the day I met my wife (16+ years ago). Everyday isn't a bowl full of cherries but every day is full. Career, mortgage and kids have also made me a lot more grounded, happier and satisfied. . .don't get me wrong, I still want things but, I rarely have time to sit around and dwell on them. . .some of them I'll have, some of them I'll never have. . .it's OK, though. . .I still keep pushing myself
Turning 40 (I'm 41 now) changed me too. I started to realize that the ride wasn't going to last forever which forced to reach out a little further and down a little deeper and, to pay more attention to those things that really matter like family and friends. I still have bad days from time-to-time but the good far outweighs the bad.
Are you committed to anything important in your life??
