How about this? You can't change the past but you can ruin the present by worrying about the future. This was in a forward e-mail I received this morning.
I have a lot. "It's not your fault" ...as in you can't help it that you have this brain disease. Another motto I use alot is one I've seen here frequently, Alrighty then!
It is what it is is one I use oftne, but the ther one is, You've got to laugh or else you cry. I find that so true in this case. You have to find the humor in this insanity, or you'll spend your life crying.
