Remember that? Buzz and Woody are strapped to a rocket and Woody thinks they're about to be blown to smithereens. And remember what Buzz Lightyear replies to Woody's wailing "this is the part where we blow up" line? NOT TODAY! Buzz has a plan. It's a great plan with a logical and attainable conclusion.
I need a Buzz Lightyear and instead I get the truth. What is the truth? Simply, that nobody will negate your anticipation of failure with a NOT TODAY and show you how to glide effortlessly from certain demise to your heart's desire. It just doesn't work that way.
