Do you need it to be specifically Tony inspiring Steve to heroics? Or just him inspiring Steve in general? Because I would take a different approach to the latter if it was possible. While, yes, Steve does help inspire Tony to heroics, which is sometimes what he needs, I think that Steve has a different personal struggle, in that the heroics are NOT necessarily always good for him. So, Tony's influence on Steve is more toward caring about himself as a person rather than just being everyone's hero, and also questioning himself and facing his own stubbornness. I think there are more canon examples of that if you need this!
