On my wall i have a note that reads “I lived as I dreamed.”
That little saying/message originated from the movie Neverwas, and every time I look at that note, It reminds me that some things we worry about are just not that important (some certainly are but not all), it also reminds me to keep my childhood dreams alive.
Related to the above I recently came across a talk from Carnegie Mellon professor and alumnus Randy Pausch (RIP), which once again puts things into perspective. I hope you enjoy his talk.
