Frugal vs. stingy
It's true: necessity is the mother of invention. Being backed into a corner is a great way to force yourself to come up with something original.
On the other hand, you never want to be in a position where you're competing on price alone, cutting corners to maximize your profit.
There's a fine line between being scrappy for creativity's sake and sacrificing quality of product by way of scrimp.
Being thrifty is a great thing to do when it makes your product or service better, not when it takes away from the experience your promising to make.
