As we get older I think we look forward to change about as much as we look forward to a trip to the dentist. (Sorry Jo)  I usually like to shake things up once in a while. Try something different like learning sign language or just driving a new route to work. Most of the time however I am like everyone else, a creature of habit.
When you change something you can't just do it once, especially if you want it to stick. The hard part is making sure that change is permanent. Whew.... that aint easy.
If it is something that is important to you or a change from something you done a certain way for a long time it becomes even harder.
But I have found to try a new experience, for me, isn't as hard as thinking a certain way about something.
I can change how I eat and what I eat, for instance, easier than I can change my mind. I only eat a few times a day but my mind never stops. I am always willing to try anything even if it means changing something very important to me..... even...the way I think.
