All of the things you've mentioned above are very important but my favorite is Service. Giving is one of the most fulfilling things we can do. Why are we here anyway? To make money for us? To make us happy only? To give ourselves only? Nope. We are here to help others, to create connections, to love, to serve. I resonte with this part of your post so much because in the past I was kind of greedy. I had the most interest in myself. After some time I came to understand that giving is the key to a happy life. The best part? When we give, it will always come back. Awesome post.
