Here's a little paradigm shift for you to practice on. Perhaps happiness shouldn't be the primary goal. Try the idea that it might be enJOYable to cook, to set the table, to see your family, rather than the idea that you'll be happy after dinner's done and cleaned up. My guess is that such happiness might last a couple of seconds before you look around and see something else between you and happiness. Joy, though, can be ongoing, and can be felt before, during and after the meeting of goals.
Enjoyment is seen nearly as a sin for some people.
You're not here to have fun, you're here to work. If you see an old friend that can bring pure, tingly joy for which there are no words. If you practice noticing and experiencing joy, if you take a second out of each hour to find joy, your life improves with each remembrance of your new primary goal. You don't need someone else to give you permission, or to decide whether or not what you thought gave you joy was an acceptable source of enjoyment. If it's not fun, it won't stick.
