This speech is highly motivational to me, when I first watched it in 2007. May be this could help you also. May be you need some information about Steve Jobs to understand this video.
Some takes for me from the speech,
- Never stop on hurdles, it leads us to match dots when we look back to our life.
- Love your work, and
- Send positive energy to others and it also returned back to you.
