Podcaster Talks Again about the "Hundred Days"

On his Mindset Mentor podcast, personal development coach Rob Dial tends to recycle the same topics over the course of time.  That's good...there's such a thing as being all over the map and disjointed with your message: better to keep it to a few profound principles.  Last December he had a show about the "hundred days"...the other day he discussed it again.  In a nutshell, Dial maintains that the key to success crucially depends on maintaining consistency in an area...and doing something daily for one hundred straight days is a good way to attain it.  As with the other podcast on this topic, he brought up the example of comedian Jerry Seinfeld, who maintained that he kept the habit of coming up with a set amount of new material each and every day...and marking his progress on a big calendar.  So according to Dial (and Seinfeld), you first pick a specific endeavor...not too cumbersome...to habituate yourself to doing, preferably one that if implemented could make a real positive difference for you.  Then you do it every day for a hundred straight days, refusing to give in to pressure from without or negative self-talk from within to take "days off".  And finally, RECORD your progress, either on a Seinfeld-styled calendar or in a journal.  Oh, and Rob Dial strongly hints that it's best to work on one thing at a time for the hundred days.  I don't know which aspect of this is more difficult: coming up with one high-leverage goal or realizing the enormous number of things I want to change for myself.  I think it's a good idea, in any case.  I've done this sort of thing already although not according to any formula, and it works...
