You know, tiny, I can relate a bit I think. I'll be 51 in March, hubby 48. We just got our retirement horses and it has occurred to me a couple of times, WTH were we thinking! The things I did when I was 30 years younger I know aren't going to happen today. I'm much more aware of my mortality. I questioned the wisdom of getting younger horses. Even though my brain still functions and I remember what I need to do, my reflexes aren't what they were AT all.
A few days ago I was down in the pen with Zoot messing around with him when it suddenly hit me. I'm no longer in a race to "do" anything. I can and will take my time with him and make him the best horse my abilities will allow. Getting out on the trail will take time and it wasn't the "ideal" situation we were looking for but here's the thing ... now I get to enjoy the process. And THAT makes it so much more worth while.
