When you're young, you're idealistic. As you grow older, you become more realistic.

What is it that sets aside great people from the mediocre masses? What propels them to have beliefs so strong they're willing to sacrifice their lives? What keeps them going when the future is bleak? What keeps them pushing even when they no longer have control over their movements? What role does the family have to play in their greatness? Why don't they ever reach a point of saying 'enough failure is enough'? Why have they never succumbed into leading a mediocre (read: peaceful & stable) life? Where do they get such strength from?

Kids are urged to 'be realistic'. But idealism is the forefront of change. And everything's changing.
