Years ago I came across “Thumper’s 70:20:10 rule for work”. The original website no longer exists and it’s not clear what the source was in any case. But as best I can tell, it’s a parody-variant on a ratio that’s often trotted out for corporate/business learning.
Enough background. Here’s how it goes:
70% psychological (keeping it together mentally),
20% logistical (moving things about in a timely fashion), and
10% tactical (jumping out of the way of other people as they stress themselves out)
