You are right…and wrong.

You are right that most of these its have been made in the crucible of practice where your wrong is that you can just skip rigor and roll your own without consequence. This is especially true on the UX & design sides. Research by its nature requires rigor. Rigor requires education. Anyone faking this and succeeding are either a) lucky. b) see a).

The reality is that you can’t just gloss over decades of learning human social and psychological wisdom and hope you get it right.

As Eleanor Roosevelt said, learn from others because your life is too short to learn eventing on your own. And quite honestly to learn from other takes effort and had a method of its own, too.

I think your Just DO IT line is inspiring, but dangerous.

Oh! I was going to say that org change is the hardest part. Transformation is a PITA.
