I'm unfamiliar with Lean and Agile. Any chance you could point me towards a formal introduction on these?

This very much aligned with my personal experience - I'm currently somewhere in the middle of "Building Automaticity". I'll need to take time to read and reflect on the more detailed posts, but as @Hazard says, this seems potentially useful to the beginner - in this case myself!

Now I'm curious about Dark Side Epistemology spells...
