In my opinion, jealous adults have never learned how to be happy. My definition of happiness is the ability to be satisfied with what you have. My mom taught me that. She had many sayings from her life that have been given to me. (She is 90 now, and when I repeat ones that I loved, she doesn't quite remember) So, I pass them on to my son, and now my granddaughter.

Plenty of people who seem to have perfect lives, are not necessarily happy and many others who seem to have little are perfectly happy with what they have.

I'm going off topic a sec, but want to share my favorite saying of my mom's: "You are not better than anyone else, but you are just as good"
