The "problem" is framed to support the author's sentiments about discipline. "Motivation vs discipline" is not a useful description of the problem at all ("x vs y" arguments seldom are). In my experience, people who frame the problem in this way are accustomed to doing what other people want them to do. They get depressed and unmotivated and wonder why they can't "make themselves" do things. So they decide to misuse the idea of discipline to complete their transformation into an automaton! Try this instead: Do whatever YOU want to do. Find what motivates you and pursue it. It really is that simple.
