My twitter bio once included the line, "my purpose in life is to find my purpose in life," and the sentiment is still true. I have a more immediate purpose of establishing an income source but the wider long-term purpose is wide open. The frame of life purpose might be unhelpful. At this moment I'm certainly in the explore half of the explore/exploit frame for how to live. Many accomplish a series of explores/exploits, sometimes in parallel.
I'm thinking about this now because the topic will still be pertinent once I find work. I don't imagine that my mission is to optimize something or other for a company.
I'm drawn to the problem of poverty. To me it's the problem with the highest global upside. Helping the next Great Human avoid death in infancy or from starvation is such an obvious thing to do. But I don't know what to personally do about it besides work to improve my skill set so a potential inroad may reveal itself later. And I am doing that.
I'm drawn to the problem of mental health. Again, enormous upside. Imagine everyone's mental baseline bumped up by one percent. That's huge. But again I have the same problem with the problem.
I'm drawn to the meta-problem of people who lack a mission. So much potential energy laying dormant. Same same, but different, but still same.
So my mission remains uncertain for now. I'm open to pitches if you want another brain working on your mission.
