What the author calls "impulses" the Buddha called sankhara, or reactivity. The ones the OP is talking about are minor reactions.<p>These reactions do indeed impede our progress, as when our actions are driven by reaction we are not fully aware of what's going on around us. I first recognized the practical implications of this playing billiards - when I would strike a ball and miss, I would feel slightly dejected, and neglect to analyze what I just did to learn from it. When I would strike a ball and make it, I would feel slightly elated, and neglect to understand what I just did to learn from it.<p>My game got a lot better when I started playing the game, fascinated but detached from outcomes. There are a remarkable number of ways to strike a ball wrong - and it is interesting to consider <i>why</i>, having learned the game sufficiently, one would ever strike the ball wrong. Where does the variation creep in? Why, if I examine a table and decide to put the cue ball "just so", can I not do that? The answer, of course, is that there is countless non-verbal data that your body is sending you on each stroke - feedback from your bridge hand, the hand on the cue, even your stance and the feel of the felt all factor into this.<p>If you are attached to the outcome, all of this goes out the window. There is nervousness, fear, and excitement instead of systematic understanding.
