Maybe it was when you were fresh out of college, starting your first professional job. You hung out with friends in your free time and fell in love with the person you eventually married.
Maybe it was your college days, when you were carefree and life was one big party.
Or maybe it goes further back, to your childhood and a time when your biggest worry was how late you'd get to stay outside in the summertime.
For some people, the "good old days" are a combination of all of the above. Their nostalgia can be confusing, since it varies from one day to the next. Whatever the era, the problem is that people are spending their time looking back instead of enjoying what they have today.
Recently as I rewatched the finale of The Office, Andy said something that resonated with me. I even remember hearing it the first time the episode aired and thinking it was one of the most beautiful things I've heard. While working at Dunder Mifflin, Andy looked back nostalgically on his days at Cornell. He left Dunder Mifflin to work at Cornell and spent all his time remembering "the good old days" at Dunder Mifflin. His profound statement was this:
No matter how old you are, you'll never be this young again. Your kids will never be this age again and (if you have them) your grandkids will never be this age again. If you achieve all your dreams, you may even look back at today and wish you'd enjoyed "the climb" a little more.
Maybe in 2016 we should spend less time looking back and more time looking at what we have today.
Enjoy today as if it were one of the good old days you'll look back on someday.
