![“[...] you shouldn't be uneasy about any parts of the architecture. It shouldn't contain anything just to please the boss. It shouldn't contain anything that's hard for you to understand. You're the one who'll implement it; if it doesn't make sense to you, how can you implement it?” quote by Steve McConnell](https://sms4smile.com/quotes/img-quotes/0a6/steve-mcconnell-11957_architecture_you-shouldn-t-be-uneasy-about-any-parts_574744.jpg)
