Random quotes from memory (so not exact quotes): "Just remember that the only failure is the failure of not trying. If you focus on doing your best then you won't have time to focus on losing. Life is a journey. Just enjoy the journey. The most interesting thing about a postage stamp is the persistence with which it sticks to it until it gets there."
Those "little old ladies from the community" are like postage stamps...after all these years they're still sticking to it "until they get there" aren't they...still taking the opportunity to improve on past attempts. Still not quite there but having a grand old time trying.
If you lose this time then so what...your goal was to do your best and you did it...and that's a win! If it turned out not to be your best then look at it this way...it was an opportunity to improve yourself for next time. And it was an opportunity you didn't pass up. Pat yourself on the back for trying because that's BIG.....HUGE!
Oh, and your Grandma's fudge and your chocolate chip cheesecake sound awesome!
