Batman teaches us an important lesson: Heroism is within your reach.
You don't have to have super powers.
You can accomplish your goals, you can be the person you want to be, you can
pursue your life's mission, you can protect people, you can avenge your
parents' death if you have the dedication, if you put your work first, if you
train for hours upon hours a day, if you cut off all contact with friends and
family, if you never waver, if you use your brain to its fullest ability, if
you invent all kinds of whiz-bang gizmos. If you do all that, then you can be
a crime-fighting, oppressed-defending, awesome super-hero.
Also, if you inherit a bajillion dollars.
