Quotes:
• Beauty awakens the soul to act. — Dante Alighieri (1265-1321) Italian poet
• Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that. — Dr. Martin Luther King Jr. (1929-1968) American preacher & peacemaker

Tip: A lot of drive is just sticking with your ideal past the zeal, past the enthusiasm, past the requirement, on to drudgery leading directly to the accomplishment.
