If you want any perspective on life, you have to listen to this podcast immediately. All of it is great, but I am talking about the part from 41:39 to 48:22.
If you don't have time to listen then my summary is below, that surely will not do it justice, but here goes:
Remember that your time on this Earth is fleeting. Thinking about the history of human beings, if it was a 700-page book, you would only be alive for a sentence at most. This is the most exciting time to be alive and most people will not do anything that would make it into that book. There have been so many amazing shifts in technology and communication that it is very unlikely that you will make an impact big enough to hit the 700-page highlight reel of human history.
But you can still make an impact.
To your friends. To your parents. To your children. To your teachers. To your mentees. To your co-workers.
You do not have much time to be alive. Why must we waste any of it?. Each day is fleeting and we must make it our own.
