Well, me too. I'm often inspired by great films and great music and achievements of others. But, they're momentary inspirations. They don't last enough to make a significant impact on me.
So, the way I measure inspiration is when I have one day to study for an important final and it's a lot of work or a ten page paper and it's due in 15 hours. What propels me to put in serious time and study hard is what I consider REAL inspiration.
I don't think back to a Michael Jordan quote, (no offense to ray of course) and propel myself.
