There are different kinds of simplicity. Some are better than others.
The master instructor knows the details but coaches with simple instructions: stand tall, breath and so on. The master teacher understands every word of her text but concentrates on the central idea. The ability to explain complicated things with clarity is a mark of mastery.
Unfortunately, it's sometimes those who have mastered the least who talk the most.
Simplicity is easy. Clarity is earned. We earn clarity by confronting complexity.
