Many people have their own parameter to judge the success and happiness. Majority of the people judge it directly to the monetary gain and the material gain. However few people are happy without having enough money and material gain. So there are variations on how to determine it. It totally depends upon individual. In my opinion the good physical health, good financial health and the good family, friends and relatives connection/relationships are the measurement of success and happiness. If we can maintain those health and relation I think that is the success and happiness.
Only the financial gain is not the success in life. Obviously it is necessary to have financial gain however that has to be in a balance way. It means while longing for the money, one should not ignore his/her health, family and friends. A person who earns so much money and fame but at the end of the day, if no one is there for him/her, that is useless. So the most important factor in life is the balance among ones physical and mental health conditions, family and friends relation. People cannot stay at the top without the support of other people.
As I mentioned earlier there are as many variations as people are there in the world. Some people believe in giving to be happy. Some people believe in making their career on the top. So there is not exact parameter to it and it is totally depend on the particular person. It means success and happiness are related to the nature of the people. Some can be happy with what they have and some longs for more.
