I want to introduce the next section of the course, which is going to be all about eliminating interruptions. Because anytime you get interrupted by your phone or whatever, you can't switch your attention. You just destroy your focus. And the quality of your focus is directly correlated to the quality of your work. The more you focus, the more you the better you'll problem solve, the more you'll think deeper about a problem. But then you'll think deeply, deeply, deeply. And then, ping. Something goes off, you're distracted, and all that train of thought just goes poof. Most of it. Not all of it. Most of it is gone. And that's why it's so important for productivity, for problem solving, for thinking, for deeper thinking, to eliminate interruptions. And that's why we're going to talk about that in the coming videos, in the coming section.
