Growing old is mostly about your memories losing relevance. Oh, not to you. The worst part of it is that you're not making new ones.
Now, my pal, Ed Brown, liked to say that youth has no concept of mortality. It's not that the concept was over my head while I was young. I just didn't care. I look around me now and worry that youth places no value on memories. Heck, there's a new one around every corner.
Well, I have advice and I'm pretty sure that all my young friends have been waiting with bated breath. Take notes. Pay attention. Write songs. Take pictures. Laugh. Hold hands. Don't ever withhold love and don't waste time or energy on a grudge. When it's love or money, go with love.
Your wardrobe will go out of style and your stuff will rot and rust. Keep your memories handy and share them when you can.
