But I really have been trying to work on it. More than anything I have come to realize that my worrying (my Dad is a worrier and my G-ma is a worrier) will not solve anything.

My sister is the optimist. Her hubby is the more pessimistic one.
My hubby is the more optimist than me, but only slightly so.
I just say I'm a realist.
