Exactly, happiness usually happens to us, as an internal response usually from an external stimulus. But it can be self-generated from inducing thoughts that provoke and summon emotional responses as well. I've talked about that in a post last year about happiness too. Forgot to add it in this one hehe. Happiness, joy, and all emotional states are internally felt, within. They all come from within, but are triggered either by self-induced feedback in consciousness (depending on us alone), or from an external source that motivates such a response. Positive and negative emotions are not meant to be everlasting. They all depend on us, and how we are conditioned or willfully choose to respond to things. We can choose to self-stimulate positive feedback to generate emotions, or be influenced by external stimulus, but it always involved us in either case. So I disagree with part of your assessment on joy. Thanks for the feedback as always :)
