Happiness is loving your job. I have to tell you I have had a few jobs in my lifetime. I also have to tell you that the one I have now I absolutely love. I love working with kids and their families one on one to make things better for all of them. I love the people I work with. We are all interested in helping people including one another. They are a great support system and I love them all.
I suggest if you don't have a job you absolutely enjoy doing...find one.
