Five minutes a day is not some kind of magic number or formula, but merely a stand-in for the idea of incremental, rather than drastic, changes to create new habits and routines.
You might remember a post called Keep Dreaming, in which I wrote about the difference between greatness and being a Name. Small Giants, for all that it is a book about entrepreneurship, is really talking about the same idea: that success and greatness are as much matters of definition as they are of achievement, and that greatness and success do not lie only in what could be considered standard or popular definitions of the concepts.
I've seen a lot of commencement addresses for the class of 2020 recently, an outpouring of advice prompted by the lack of a more traditional ceremony because of the coronavirus-related lock-downs. If we're being completely, brutally honest, most of them have similar themes, and say similar things, and convey similar messages, whether they're from a celebrity, a political figure, or a businessman. I generally skim through a few of these as I'm reading the newspaper, but one title, or rather subtitle, caught my eye. It didn't catch my eye for being resonant with me, but rather because it was so completely contrary to any advice I would ever give anyone, if I were in any way qualified to give someone advice. It was talking about the important of letting go of myths of greatness.
