I'd build a compound in the woods and fund/train a group that would function sort of like a secret intelligence apparatus except instead of serving capital it would serve the revolution. Like a reverse cointelpro doing covert ops against fascists, pigs, capitalists and politicians.
Get my own affairs in order, then get all the firearms practice I haven't been able to do due and get in contact with local leftist orgs to bankroll them. I don't really see myself as leadership material, would much rather just help people who are good at organizing.
