This year, I begun wearing a sweater on powder days, same sweater and I haven't washed it once this season (mostly because it's dry clean only), and I've had some great pow days this year.
Also when I used to compete, i used to growl/roar to get amped up and aggresive right as I dropped in at every event even big air events.
And when I am about to ski something that has my balls all clenched up and has dangerous consequences if you fall, I make sure to tell whoever I am with that I love them.
