It's always important for me to remember #5 on my list of 10 Basic Mental Aspects of Orienteering: Do not underestimate anyone. Everyone can beat you.
The Classic Champs have not happened yet, dude. Anything can happen. I know victory is not guaranteed for me, particularly if you and others train hard. But I love the challenge. Plus that's exactly what I want: the whole group will train more and push harder because the difficulty is raised.
All that being said, bring your A-game, man. Because I'm bringing mine. It's going to get real at the Classic Champs.
I've always been a fan of that list of yours. #2 is my fave - if things don't go the way you want, look inward not outward, take responsibility, make no excuses. Be better.
