I appreciated this video from Harvard professor, Dr. Arthur Brooks. He describes that happiness is a direction, not a destination. He goes on to say that one of the biggest mistakes people make is thinking that happiness is a feeling, and continually chasing that feeling.
We should instead see happiness more like a project that we can work on every day, where the big things that matter in life are: faith (a way of seeing the world, a philosophy, or a religion), family, friendships, and work that serves others.
That feels like a worth direction to travel in.
