Great post Chris.  Couldnt agree with you more on the power of keeping our purpose in front of us.  It's the Profound Why - why are we working so hard, spending so many hours away from loved ones - for what higher order reason?  When we know our purpose and keep it front and cetner in our lives it gives our work greater significance, thus greater meaning, and so sustained motivation.  And we have a choice to live everyday in support of, or in spite of our values.  We all inherently know what to do here, but it is all too easy to lose the plot on this - the for the reminder!
Well done!
