All the life hacks so far are about care of the self. Ultimately, though, it should really be about service to other people as well. If you are struggling with your own issues, you are going to be self-centered for a while, because you need to help yourself first.
For myself, the first thing I am doing is being a mentor to two students at my university through a program through the deans office. I will see how this goes and then increase my service activities. The other thing I want to do is a poets in the schools thing.
