The what I work on post was also partly trying to answer the question of what is worth doing.
The most obvious and not necessarily useful answer is to provide Maslow's Hierarchy of Needs for all beings. What I like to do is build projects on the Internet. But does that have enough meaning? Providing housing and clothing and a clean environment is a basic need. There are other needs, higher up the chain, that are important too. When someone has the basics one can move on to increasing compassion and understanding between people. Conflict resolution.
Economic improvements is an area of interest. Why does housing cost what it does? Is there another financial construct to provide privately-owned housing? Co-housing has introduced 'village' concepts into the Feudal private ownership system we are used to.
that's all I got for now...
