Yes, Agile is a lot about Getting Things Done (the real meaning, not the book, see below). It's about getting trough procrastination too. I've found that Agile methodologies tend to solve mostly psychological problems. In fact, most problems we encounter in software development are not technical, but psychological.
I have many projects where I'm the only one involved, and yet I've my own backlog, sprint backlog, my own information radiator, I apply the same "done" definition rules, reviews, retrospectives, ...
But no, I'm not doing standups meeting alone or with my cat :)
I've read many books about productivity improvements before I discovered agile methodologies. And what I've observed is that agile is very similar to them.
For exemple, Scrum is a lot about Getting Things Done, and others well known books on the subject.
That book certainly saved my life at a certain point. So get it and read it. It will helps you "get it", I mean, understanding what Agile means. Trying to do Agile not understanding it will leads you to failure.
