One of the best things about getting older is that you care less and less about what others think of you. I used wear those spike-heeled, pointy-toed shoes that had to have been designed by a man because nobody who actually had to wear them would have ever created such pain-inducers. I would take them off whenever I could - when I was sitting at my desk, my shoes would be off until someone came in my office and I'd quickly put them back on. When I thought I could get away with it in a meeting, I'd slip those torture devices off and wiggle my toes to get some life back in them. I dreaded walking very far because I knew that my feet would be killing me before I reached my destination. Why oh why did I put myself through such misery?
Finally, in my 50's I had had enough. My feet were constantly aching and, frankly, I wasn't 20-something anymore and didn't need to prove anything. I felt a little odd when I first wore my "sensible" shoes to work but my feet felt so much better, comfort gave way to vanity. It was a relief to let go of what I thought I needed to do and accept what I really wanted to do!
Since then, I am concerned less with what people think, whether it's about my appearance or behavior. I realize what's really important and what's not - I suppose that comes with experience and maturity - and others' opinions about me is definitely not.
