We all love you @mesunil2010
In my opinion in order to be happy is to be contented on what you have and appreciate everything that you have. Your family is a good way to get motivated while working. Going out sometimes or spend time with friends is a good way to be happy.
An attitude of gratitude gains altitude.
Smoke some weed, do what you like to do and stay away from drugs.
for me making music is a happiness
If we talk in the context of work: Do creative things first. This will help you better do work which you love the most.
