Survey? Do you think contentment is the only key to happiness? If not, what else? If yes, why?

An interesting question, but I'm not sure how to answer it.

To begin, one has to define happiness; and I'm not at all sure what it is. Could you give me your definition? Is it the persistent lack of pain, and perpetual presence of "good feelings"(whatever they may be)?

I feel that contentment is a desirable life value to be sought up to a point; but not necessarily should be paramount in ones philosophy of life.

For me the most important values in mine has always been: (1) to comprehend the essence of life: (2) experience unconditional love: (3) and create something beautiful and enduring.

One can be perfectly content just sitting on the couch every day watching TV and living comfortably, having a good family, good food, and good friends. It really depends on how one is brought up - I know many people who are content living simply like that.

For me, a sense of fulfillment is key - fulfillment in every sense of the human being - mind, spirit, body, and soul. I believe humans are aspiring beings - they are quite goal-oriented and cannot function optimally without goals, no matter the extent. Knowing I have struggled for something and achieved it brings me great happiness. Also knowing I have affected another human being by connecting to them in some way brings me great joy.

The word contentment to me is very passive - it seems as if one needs to compromise something or settle for something to be content. Perhaps I have misunderstood. Well, maybe if one is content about one's bad situation, he or she has no desire to better the situation. That, I believe, is not true happiness.

no it can be love as well

It sure is
