Happiness is something that you have to work for. Now, don't be put off. This state of mind isn't terribly elusive, it just requires effort. Positive thinking is a big factor. Being able to "think happy thoughts" (honestly Peter Pan wasn't too far off) makes a big difference in how often you feel happy.Happiness, like most things, requires a willingness to become. A willingness to put in that effort, to get rid of negative influences (e.g. people, activities), to believe you deserve it.At least, that's what I think.
