If you are into programming or software development, here I discuss three basic principles:

1- DRY: Don’t Repeat Yourself

2- KISS: Keep it Simple Stupid

3- YAGNI: You Ain’t Gonna Need It

The difference between You ain’t gonna need it and DRY in software development is that the latter is reducing complexity by dividing a project into manageable components, while the former is reducing complexity by reducing the number of components. YAGNI is similar to the KISS principle, as it strives for a simple solution. However, KISS strives for a simple solution by trying to implement something as easily as possible; YAGNI strives for simplicity by not implementing it at all!
