Problem: how do I feed myself and my family and community good food, and ensure adequate shelter?
Solution: working with your family and community, take care of your natural resources in a large enough area to sustain you (and also accepting that your population will be regulated by the carrying capacity of the land and water), and practice ways to sustain yourselves for generations.
Doing this in a healthy way, together, is meaningful and likely to lead to a peaceful death with no regrets. If you really don't care about the money, consider activism. I'd say your chances at lasting impact are greater in the existential realm. Who is going to care about Facebook or Twitter in a century? With a strong oral tradition, your community's descendants may care about your leadership during catastrophic climate change.
