George B. Thomas talks about happiness and managing expectations as keys to personal growth. He explores psychological and philosophical ideas about how our expectations shape our lives and what it takes to actually change.
This idea of setting your route or setting your GPS of your life. There's a very deep level connective tissue to the word happiness. If you have healthy expectations, it may be easier to live a happier life. If you're setting your own expectations and following your expectations, it may be easier to live a happier life. If you're driven, follow, and even have like Pavlov's dog response to others expectations, it might not be a very happy life. One of the reasons you might battle with this life that is not so positive. Maybe you're more pessimistic than optimistic. I don't feel the joy. I just want to be happy. Maybe this is because your expectations are one of two things, or maybe both not met and not set.
