I could not agree more with everything you wrote. I deliver webinars on happiness. The first thing I say to people is that they do not have to be happy all the time, that it is impossible to always be happy. We are allowed to feel whatever we feel, it's what we do with that feeling that matters. Also, many people are chasing the wrong things to make them happy. Want to be happier, do something nice for someone else, volunteer, spend time with people who accept you exactly as you are. Look for the pockets of joy and savour those moments.

And if you are sad, angry, frustrated, cranky, irritated, miserable then that is also okay. Your feelings are valid - what you chose to do with that emotion is what matters.
