What is true contentment in a person's life. does it really exist or it is just a word.?

I do not think 100% true contentment is possible because humans, by nature, always are wanting for SOMEthing. BUT, I DO feel like I DO have true contentment (which I work on daily to cultivate....). It is NOT "just a word" to me. I actually feel it. Maybe not in ALL areas of my life, but definitely in quite a few areas. I sure do have a lot more then I ever did when I was young. I think contentment comes with age and wisdom, and life experience. It is really, really, difficult for me to believe that a youngster can have any. It IS probably just a word for THEM.
