At the start of the movie Dead Poet's Society Mr. Keating says, "Carpe Diem, lads. Seize the day, make your lives extraordinary." The scene is set in front of photos of men who died in the First World War, and he's saying to them, "Don't be boring. Don't just waste your life, make your life extraordinary. Live on the edge."
But the truth is in life these days we get into the day-to-day grind of raising families or a busy job or something. One of the things that can creep in is this comfort zone, which acts like a bubble. It can be hard to break out of, because it's just so easy to stay just where you are and not really ever do something a little bit on the edge.
What we mean by living on the edge though, is not necessarily doing something crazy or dangerous. What it really means is to do things that give you significant energy, that break you from the normal bubble and put you into a space that I just kicks you out of the comfort zone.
And it's not all the time, but it's just things that put adrenaline back in the bloodstream.
