Night classes are hard enough, but night classes that are 5 1/2-hour cooking labs take it up a notch. And having a 9:00 a.m. class the next morning takes it up another notch. And doing it all over the next day? Whew.  For the past two nights I’ve had about 10 hours of sleep total, so my edges are a little frayed. Even so, I am working, rather feverishly at this point between classes, on writing a Value Proposition for a college-sponsored competition called The Big Idea Elevator Pitch.The idea is to pitch your business concept by defining your product as the answer to a perceived problem, and then discussing its viability in terms of target market, competitive advantage, and potential for profitability. I’m pitching my bakery concept. The prize is worth $500, due tomorrow, so I guess I can handle another night of little sleep. Just don’t let me handle sharp knives in lab tonight.
