This document discusses concentration and provides strategies to improve it. It begins by defining concentration and noting that everyone has a natural ability to concentrate, though lapses can occur. Poor concentration is usually due to distractions, both external (e.g. noise) and internal (e.g. worries, boredom). Maintaining concentration involves minimizing distractions, taking regular breaks, reviewing material, and establishing good study habits and routines. Simple techniques like focusing on breathing can help train the wandering mind. With practice of these strategies over weeks, concentration can be improved.
