I like the first two points, and I understand the 3rd point about making the stakes personal, but unsure if I want to give him a wife and child, merely as I have a potential idea for a love interest. So, need to work out how to increase the stakes so maybe I need to think more along the lines of Indiana Jones or Star Wars where there isn’t a family per se, but the threat is at a high level…e.g. Nazis win the war if they get the Arc or the Rebel Alliance is destroyed if the plans of the Death Star fall into the wrong hands.
