Can you shed more light on doing one thing at a time? Is this about removing distractions while you're trying to learn or is this as much about picking one topic to learn at a time? IE don't try to learn to play the piano and learn to speak Chinese in parallel? My assumption is that section 1 is about the small distractions but I was also wondering if the research indicates anything for multiple courses of study in parallel.
