From John Maxwell
Four truths about passion:
1. Passion is the first step to achievement — Your desire determines your destiny. The stronger your fire, the greater the desire — and the greater the potential.
2. Passion increases your willpower — There is no substitute for passion. It is fuel for the will. If you want anything badly enough, you can find the willpower to achieve it.
3. Passion changes you — If you follow your passion — instead of others' perceptions — you can't help but become a more dedicated, productive person. In the end, your passion will have more influence than your personality.
4. Passion makes the impossible possible — Human beings are so made that whenever anything fires their soul, impossibilities vanish. A fire in the heart lifts everything in your life. A leader with great passion and few skills always outperforms a leader with great skills and no passion.
