There’s lots to change, I’d make it my business to do so. Funding would come from popping back, buying something, going forward and selling it, usually to rip off twunks like bankers, I’d invent Facebook before Zukkerburg,? Bet on Red Rum, put 1p in the bank in say 1664 whilst visiting France to see Kronenburg getting invented and so on.
First, I’d kill Hitler though, in 1914 in the First World War moments before offing Blair at birth.
