there's nothing to worry about --- ever!!
either you have control or you don't.
if you do, take control; if you don't,
dismiss it. don't waste your energy on worry.
over the last several months, i'd say i spent a fair bit of time worrying about the outcome of my dissertation defense, but as the quote points out... i had control over my destiny. i agree that worry over things i have no control over is pointless, but i feel this goal was something i had control over. focus energy on things that are possible to change.......
