Building a long-term human settlement in space (i.e. moon, mars).
I love the human experience and I believe that we need to get many more people and many more resources to extend the life-span of humanity. And currently the biggest blocker to that is that all long-term human settlements are on Earth.
I'm currently kind of working on it by working at a startup to collect capital (money/network) towards this.
To actually start getting traction on this I need to collect a lot of money, get investor trust and actually figure out how to make it profitable (i.e. what technology is needed, etc).
