The Agile founders had it right, one size doesn't fit all. What the founders perhaps didn’t foresee, or couldn’t agree on, is that in order for the world to scale and consume their wisdom, it had to be packaged as concrete practices, not as abstract classes with virtual methods to be defined in context. And to the proponents of Agile Scrum, give them their due, for their part, they made it concrete – Agile Scrum has been packaged and delivered. Yet much work remains to realize the promise of Agile, which in summary is, the realization of wise use of lightweight development practices and workflows that flexibly adapt to the changing and evolving needs of customers.
From Sextus: The idea of what it means to live in accordance with nature; gravity without affectation, and a careful regard for the interests of one's friends.
Even if you were to live for three thousand years or ten times as long, you should still remember this, that no one loses any life other than the one that he is living, nor does he live any life other than the one that he loses, so the shortest life and the longest amount to the same.
Cast everything else aside, then, and hold to these few truths alone; and remember, furthermore, that each of us lives only in the present, this fleeting moment of time, and that the rest of one's life has either has either already been lived or lies in an unknowable future. The space of each person's existence is thus a little thing, and little too is the corner of earth on which it is lived.
Everything that is in any way beautiful is beautiful of itself and complete in itself, and praise has no part in it; for nothing comes to be better or worse for being praised.
The cucumber is bitter? Then cast it aside. There are brambles in the path? Step out of the way. That will suffice, and you need not ask in addition, "Why did such things ever come into the world?"
