At my work our office manager sends out a "Quote of the Day." I don't always pay attention to it, but it caught my eye today.
"Happiness is not in our circumstances but in ourselves. It is not something we see, like a rainbow, or feel like the heat of the fire. It is something we are." -John Sheerin
It is true. Our goal isn't to get to "happiness," but to become a "happy" person. There is a difference. I know it deeply. It becomes part of you as you work for it, and it feels fantastic.
Take it from someone who is trying.
You should too.
