A marathon is one step at a time. Heroics are one good choice at a time - choices to do the right thing even when it is the harder thing to do. You're made of the right stuff kid, I believe in you.
Heroics are always small. They are the letters on a page that form a novel. So be confident in the small ways you become better, they are the way onwards for you and others.
Your heroics are legendary. They will join the heroics of the ages, the best role models, and aid in guiding the formation of new heroes, new titans that will together build the gateway of Earth's golden age.
All this heroics is voluntary, eh? Well, what the hell else am I gonna do with my existence? Ride on. Ride on. I'm in.
