Reverse Motivation or Earth to Steve Jobs

Motivation. I suffer from a habitual lack of it.
I'm not a complete slouch, but I've often found it difficult to begin things, even though I consider myself a fairly creative person. I fill with excitement at the prospect of a new adventure in creativity, but a combination of things seem to deter and distract me.
Most motivational speeches don't appeal to me. I feel as though they fill me with sentiment and energy that are only temporary, and I've never heard one that I can remember that's left a lasting mark.
I recently heard a commencement speech that Steve Jobs gave to the 2005 graduating class at Stanford, and I thought about it for days afterward. The title of this post is a link to the full text of the speech.
The part that got under my skin was when he said
"...for the past 33 years, I have looked in the mirror every morning and asked myself: "If today were the last day of my life, would I want to do what I am about to do today? And whenever the answer has been "No" for too many days in a row, I know I need to change something."
This line dug at me, and bothered me over the next few days. I thought: not everyone is you Steve Jobs. For many of those 33 years, you've lived a privileged life, with many options open to you that aren't possibilities for average people.
You're white, you're male, and you've had money for a long time now. How dare you imply that it's easy for people in other situations to throw off everything and change?
As I thought about it more, and became more angry, I realized that Steve Jobs' attitude really was motivating me, but not for the reasons that he intended.
For me, a good motivator is often anger. I remember a professor at York, one that I thought was amazing, giving me a copy of 'A Room Of One's Own' by Virginia Woolfe. At first I was pleased that he gave me something that he thought would help in my development. Looking back on it shortly after, I started to feel insulted.
Did this man think he knew me...? Or did he just think he knew where I might be in my development as a young woman?
Either way, he pissed me off. And, juvenile as this is, I find this kind of thing to be a source of motivation far more powerful than any poster or speech could be.
