Prophet, Hero, Herald
Prophets are defined by their vision; Heroes are defined by their effort; Heralds are defined by their impact;
You don’t have to be “the” chosen prophet, but you can still have a vision on how to align humanity towards progress. I think I’m more prophetic than heroic (more fearless in my vision-making than in my action-taking), and it’s probably not a good idea to think heraldic (to become too concerned with outcomes).
