When you say your happiness is to make people happy, i guess it’s not an honest answer because in the deepest of your heart you are missing something that can fill a hole in your heart, The Happiness its self.
When you are happy seeing your friends are married, it doesnt change your life, you only feel happy for them.
When you reach something that is not your want, but someone feels happy for, it is not your trully happiness.
Hack your own heart to know what exactly your happiness..
And Be Happy!
Dont be serious to look for it, you dont’t know when and where your happiness is..
