Well, in my experience, the only real, truly universal, undisputed truth is that EVERYTHING CHANGES. 

I am desparately afraid of looking stupid - physically or intellectually - and I want to have that lifted from me. It keeps me from expressing myself honestly in physical appearance, my surroundings and a good many of my interactions.  The fear is lifting, but it bugs me that my choices about what car to buy, haircut to have, clothes to wear, job to take, art to put in my office, etc. is based on FEAR of what other people are thinking. I'll tell you, doesn't THAT make me look more stupid - to think I can mold my life around what others might thinking of me? Exhausting. Voila.
