I had a great time in my youth and I still feel youthful. I've no desire to look as though I'm in my 20s.
The older I get, the less jarring I want my exercise to be, and I find that a long walk is equally as helpful and satisfying as a three-mile jog.
I've learned that I can't have a packed work schedule and a packed social schedule and a packed personal life; I need to just have time to myself to sit and breathe and unwind.
I try not to listen to the shoulds or coulds, and try to get beyond expectations, peer pressure, or trying to please - and just listen. I believe all the answers are ultimately within us.
