Your opinion of this quote? “I see the glass as half-empty..”?

I thought of this quote to put on the T-shirt of the Dept of Chemical Engg., A.C.Tech.

The reference is to the quote ” Some see the glass as half-full, some see it as half-empty “.

“Over-designed” is a chemical engineering term that means you design equipment that can take more load than you’re going to put now, so that the capacity can be expanded later on.
A glass half-full is over-designed – to a chemical engineer.
