In theory there is no difference between theory and practice. In practice there is.”

Yogi Berra

When you arise in the morning, think of what a privilege it is to be alive – to breathe, to think, to enjoy, to love. Marcus Aurelius (121-180)

Another flaw in the human character is that everybody wants to build and nobody wants to do maintenance.

Kurt Vonnegut AME BC announced AWARD Winners for 2014 Jim Excell, Dan Johnson, Jeff Stibbard and Mike Rylatt are the recipients of the Hugo Dummett Diamond Award. They are acknowledged for their key roles in advancing the Ekati Diamond Mine in the Northwest Territories from concept to reality, on budget, without any major injuries and with an exemplary record of northern and community involvement.
