Happiness is something hard to find... it's a lovely feeling .. it's would be beautiful if everyone would feel happy
and... I think before getting to truly appreciate happiness, one has to feel sadness, hurt and pain
sadness, hurt and pain are in the process of finding true happiness
i believe that you can never appreciate happiness in a deep way without experiencing these three things although happiness can happen without these things (but i really think one would appreciate it more if he will experience these unpleasant things)
also, i believe happiness comes from within and is a spiritual or emotional connection
happiness is more than a smile
okay i feel like i didn't answer your question ahaha i was defining what happiness is for me...
but. okay pursuit of happiness.... okay for me, there's a lot of learning in the process.. a lot of connecting with yourself and with others <--- if harmony is your aim, it's something that comes from yourself.. happiness is not just a feeling. it's so much more than that..
it's understanding what you want and need, what your goal is, what uplifts you... and then you'd be happy but happy is a temporary feeling for me (if defined as like a feeling when someone gives you a present).. people crave for more and more in life.. and so.. i would rather want to feel contented and thankful than happy because when i'm happy.. i kind of like want more and more.. and so that's not happiness.. being contented has more of a good feeling..
but if you're talking about true happiness.. then that is what i was talking about as i mentioned above
