As developers, we make different types of mistakes at different points in our career. In WordPress development, in particular, we make different types of mistakes as our familiarity with the WordPress codebase grows.

Some years ago I heard Matt Mullenweg declare something to the effect that most people repeat their mistakes, smarter people learn from their mistakes, and the smartest people among us learn from the mistakes of others. I rather like this, and I’d add a corollary: Everyone makes mistakes, humble people share those mistakes in private, and the boldest among us write them down and publish them in a blog!
