Man's mind, once stretched by a new idea, never regains its original dimensions.
-Oliver Wendell Holmes, Jr.
I for one am so glad that's true. It's a miracle. This brain of ours while small, is huge! It's big enough to grow and learn something new every single day, every minute, every second - if you will ALLOW it to do so.
We are lucky and blessed indeed. WE NEVER HAVE TO CHOSE TO BE THE SAME PERSON TWICE!
