This presentation by Scott Stratten at TEDxOakville is important. Please watch it.

I don't want to steal any of Scott's considerable thunder, so I'll just say that it's about questioning the unspoken and unconscious values that define our goals and our outlook on the world, which in turn define how we spend our time. It is amazing that as our lives change so radically: we get married, we have career success, we have kids, we get divorced, we get sick, loved ones pass; but none of these cause us to really change, to pause and consider the "values" we have that are nothing more than cliche's and catch phrases that we internalized as young kids from a baseball coach, a grand parent and a 3rd grade teacher.

It's 15 minutes long, but Scott is an arresting speaker. 15 minutes is just 1 bubble. Think of 1 bubble today that you can cut out, and invest it in watching this presentation instead. You might shed a couple tears, but you won't regret it.
