The Frontier Is Everywhere – the first video in the Sagan Series by Reid Gower: https://www.youtube.com/watch?v=oY59wZdCDo0

It gives me the motivation to work towards a goal which lies tens, hundreds, maybe a thousand years in the future.

Seeing this video puts my own selfish needs and feelings in perspective, and inspires me to do my little part in making humanity just a little bit better.
