I see happiness as something that we lack and people want it so bad. Should we go extra mile bringing other people down to make oneself happy? Happiness is a state of mind and you don't need to have billions of dollars in your bank account before you can be happy.
There are so many people who doesn't have happiness despite the fact that they are rich and they can afford to buy anything they need.
Happiness is hard to find and if you are opportune to have it... Share with others who doesn't have.
Do what you love as long as it keeps you going and makes you happy but I will advice you to do something that will make you and other people happy.
My take on happiness.
