Something I've noticed about my PTs: I perform better when I'm feeling better. Not like.... physically (although that helps) but mentally. I mean when I wake up and put my contacts in, get dressed, and brush my teeth just to sit in my room to take a PT. Hell, even putting on shoes helps.
We talk a lot about mindset in these forums, but other things contribute to mindset besides meditation and repetition. Not only does waking up and "getting ready" help your outlook, it gets you prepped for test day. If you only ever take PTs in boxers, you're not replicating test day conditions!
This is all to say, keep in mind other things that might give you a little confidence boost. Two weeks out (exactly)--we can do this!
