The last couple of years, I had quite a "journey" on defining what happiness means to me and I realized that community is quite an important factor. On all the places I felt "home", I felt a sense of community. Other places were really beautiful to travel to and there were lonely times when I felt so high on life, but sense of community is what made me feel truly at home in many places in the world.
There is something about being with a group of people who you value, and they value you, that just feels good. There is also the value of adding value to those people, helping them out of love and connection, not for financial gain alone.
