“Programming is a lot like construction. Imagine a contractor building a house for you without a blueprint. Yikes! You might end up with a house that has 12 bathrooms, no windows, and a front door on the second floor. Plus, it probably would cost you 10 times the estimated price. Programming is the same way. Without a plan, you’ll likely struggle through the process and waste time. You might even end up with a program that doesn’t quite work.”
