Thinking, by its very function, is a great tool for solving problems. However, humans tend to spend much of their thinking hours pondering about things far removed from their present activity.
Unfocused mind wandering slips from thought to thought with no rhyme or reason and no particular destination. It has been linked to a poor performance, higher accidents, and a less enjoyable life and yet it remains a pillar of creative thought and problem solving because of its ability to connect far-reaching ideas.
Taking advantage of your mind’s natural inclination to wander is paramount to making the most of your mental capacity without falling victim to endless streams of thoughts which build up to nothing.
