I also revisit that particular speech once in a while. It is a real treasure, and although Jobs might be gone, his words can luckily live on.
To me, I try not spend too much time looking back at all but instead focus on the present. To me, the most powerful part of his speech was when he talked about asking yourself each morning if what you would do what you're about to do that day if you knew it was your last day alive.
Yeah, that speech is a real gem. He is always an inspiration, in so many ways. I completely agree with that last part too. We should all live like that. Only then will we be able to give our best every single day.
