Am I doing this right?

You're absolutely doing it right Doc! Enjoy every minute of it, because you'll blink your eyes a few times and look around and be in your late 50's with grandkids, wondering WTH happened and where the time went! Time goes by quickly....and it's the one thing you can never get back. You're doing great.
What he said!

I'm 58 on the outside, but still feel 30-ish on the inside, and wondering to myself, "Where did all the years go?"

You only go 'round once, so don't waste a day of it!
