“Without giving up hope—that there’s somewhere better to be, that there’s someone better to be—we will never relax with where we are or who we are.”

“We all believe somewhere deep inside that we should be better, be doing more, be someone other than who we currently are. ...we feel as if we aren't good enough.”

“Optimism is a strategy for making a better future. Because unless you believe that the future can be better, it’s unlikely you will step up and take responsibility for making it so. If you assume that there’s no hope, you guarantee that there will be no hope. If you assume that there is an instinct for freedom, there are opportunities to change things, there’s a chance you may contribute to making a better world. The choice is yours.”

“Where there’s life, there’s hope.”

“We can’t leave this world without leaving a lot of detritus behind. We never go out as cleanly as we come in; and even when we come in, there’s the afterbirth.”

“We walked on the moon. We made footprints somewhere no one else had ever made footprints, and unless someone comes and rubs them out, those footprints will be there forever because there’s no wind.”
