"It takes 21 days to change a habit," according to Maxwell Maltz - and I think he's about right, give or take a week or two.
But this past weekend we saw habit change at a high level happen in a couple of days at our Speakers' Roundtable meeting - and there's a great learning principle in this story.
Too many leaders, and speakers talk about "stuff" , as in "The group liked my stuff," or "I gave them my best stuff. We generically and lazily categorize specific concepts or details or material as "stuff." So Patricia Fripp, renowned public speaker, coach and sister of King Crimson's Robert Fripp, decided to put a learning principle in place and stop this 'stuff' at our three day meeting this past weekend. (She calls it a crime against credibility.) Every time anyone would say "stuff" the person would have to put a $1 in a paper bag.
