A cardinal principle of Total Quality escapes too many managers: you cannot continuously improve interdependent systems and processes until you progressively perfect interdependent, interpersonal relationships. ↗

I think the real reason for my improvement is because I had such a long period in the off-season just working as hard as I could on all my new dives; making sure I did lots of repetition to get them consistent. ↗
The perverse presumption that places the burden of proof on the challenger of spending must be inverted, back to the rule that applies elsewhere in life: 'Prove to me why we should.' ↗
