Have you all seen this already? --Steve Jobs' Standford commencement speech in 2005? I just watched it a few days ago and found it inspiring. This is my favorite part:
You can't connect the dots looking forward. You can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future...believing that the dots will connect down the road, will give you the confidence to follow your heart, even when it leads you off the well-worn path. And that will make all the difference.
