A few pointers I've found helpful though:
1. Learn as much as you can about systems thinking and apply it to how the world works. I like Donella Meadows' book (Systems Primer).
2. Look at how you spend your time and mind (ie your work). Work on products that, if successful, would create an equalizing feedback loop (I currently work on a personal finance product, but other areas where this exists are edtech and healthtech).
3. Teach.
4. Look at how you spend your money.
5. Look for and work against any form of "impunity". No one should be above the law or beyond accountability, especially people with power and/or money. That's how things (societies, companies, etc) rot.
6. Do your part in every small thing. If you're hiring, take a bet on someone from a less "traditional" background. Speak up when something is not right even if it doesn't impact you personally. If you follow sports, always, always root for the underdog :)
