Things my mother was right about # 4

 (No there was no 1 - 3, but there should have been).

Avocados

She used to eat them and I was very turned off. They were the same name as the ugly green-ish used in kitchen appliances.

She was right. I LOVE avocados now and put them in almost everything.

I am trying to admit when I am wrong. 

FYI - It is a philosophy that is much easier when you start with something you were wrong about 50+ years ago.
