What is the most important?

Well I'm going to be a bit cheeky and choose Happiness. Because if you are happy it follows that your life is not a complete misery due to ill health, poverty, lack of friends and most of the other states you mention.

for me,, the most important is the good health because what you will do to all the things you have if you don`t have a good health,, so we need to take care of our health..

I think the most important thing in life would be success. NOt success in the money and power way, but success in the way of what you have achieved and how happy you are in your life.If you're happy with yourself and the way your life is, then you're successful and that factor can contribute to happiness and friends, love, etc.
