I do understand for all of us this questions has a myriad of answers, answers probably as unique and individual as we are as people. But I also think we can generalise a bit on this question too for instance.
Most of us that have children will want them to be happy. But the degrees in what this entails varies, for parents of sick kids, all we want is for them to get better. If we have a child who is getting bullied at school all we want is for that to stop. If we have grown up children we want them to be happy in their lives and make good choices. If we have babies we just want them to stop crying.
For those of us trying to succeed in life whether write that long buried book that is bursting to get out or that catchy tune that will be on every radio station and hummed on every ones lips or the next step on the rung of that extremely long career ladder, what is important is to get noticed, seen or heard.
Then there are those who's value they hold on things is monetary and power. They see wealth as important and have a deep need to obtain money in whatever way they are able to. They have a desire to control others and have materialistically all they can get.
Then there are those who are not happy with anything they have and that is what is important to them. They covert others, in all ways. Simply they are not satisfied with the way their lives have turned out and will never take responsibility for that. They look at others and either critisize or pick on aspects of the other persons life to berate or compare with their own. Finding fault in how they choose to live their life, jealous and resentful but hiding it behind a vale of contempt and self righteousness. They choose to feel indignant when someone is doing better than them and spend their time finding ways to bring any other person down rather than looking inward and finding happiness within themselves. These are the people I pity the most, because what is important to them is not how they can improve themselves or make others feel better, these people are the takers in life. They are the ones who buy you a gift, then tell you how much it cost them, they want constant praise and flattery, to boost their fragile ego and this is because they have no depth of character of their own to draw from. These people who look at a pretty woman and say "well she's got a fat arse" or "she shouldn't be with him she's a slapper". These people who judge, demean, belittle and have a deep need to always be seen to be doing better than anyone else, lead horrible lives. Lives lived by others standards because they can never be happy with the standards they set themselves as they can't stand it if they think someone is doing better than them.
People stop caring when you are a taker. When you are constantly wanting praise because you did something nice once and keep reminding everyone. They stop caring when you critise a person because you don't like the way they live their life or clothes they wear, or their makeup or their hairstyle, no one wants to know your opinion its boring and annoying. People stop caring when you are constantly bragging how something was bought for you or money was spent on you its not what is important in life and people truly stop caring when you constantly spend all your time trying to convince the world how stunningly beautiful and attractive you are. It shows how shallow you truly are when these things are certainly not what matters.
I accept I am not the most attractive woman on the planet, I do my hair in the morning, my makeup when I can be bothered, I could lose weight but I like food and I'm fairly healthy. I am nearly 40 I have had 3 babies who are all beautiful and I am just so proud of. I don't have a lot of money but I certainly love what I do for a living and that makes me happy. I have a man by my side who never ever wants to leave, who I giggle with, who makes me happy and I make happy too, who knows me inside out and accepts all of me (warts and all) who still thinks I am sexy, even with my grey knickers on and who I think is gorgeous.
I have no need to look at others and feel intimidated or threatened by them, I have no need to think I am not good enough because all the facts say I am, I have no need to think bad of others. But I will always feel the need to protect what I have, to defend it and to look after it because that is WHAT IS IMPORTANT TO ME.
