Quote by Paul GrahamIf you start with too big a problem, you may never quite be able to encompass it. So if you need to write a big, complex program, the best way to begin may not be to write a spec for it, but to write a prototype that solves a subset of the problem.
Quote by Paul GrahamWhatever the advantages of planning, they're often outweighed by the advantages of being able to keep a program in your head.
Quote by Paul Graham[I]f a piece of code is written by multiple authors, none of them understand it as well as a single author would.
