Everyone think they want to be happy. 

And we hope that everyone will be happy.

What is the limit of happiness?

It depends on people, but it may be unlimited.

There is a way to be happy right now. 
It's to decide the lower limit of happiness.

Why do not you try it like this?
"I could make someone smile today as well. I guess I am happy!"

At that moment, we could feel happy every time we do more difficult things.
