This is wicked dorky, but I have Confidence from the Sound of Music is my pump up song for everything. When I was job searching a couple years ago, I listened to it before every interview.

Not surprised by Georgetown nor Harvard. Bit surprised by Berkeley. Extremely surprised by Columbia: I had a bet with a buddy that Columbia would jump to 3 and tie Harvard. Looks like I owe him a beer.
I love Meditation Studio! It has short meditations for every sort of situation from an important job interview, to general anxiety, to prepping for bed on top of general meditation courses to develop the skill of meditating.
