One fast track to a happy life is meaning.
Research repeatedly shows that individuals with a sense of meaning in their lives are happier than everybody else.
A sense of meaning or purpose gives us a feeling that we are part of something larger than ourselves. This, in turn, fuels self-worth, a sense of identity, and a feeling of community and belonging.
All of these are traits that boost happiness, so you can see how meaning can be a super booster.
So all we need to do is figure out the meaning of life.
