You don't have to worry about meditation turning you into a fuzzy person. With meditation you train your mind; the exercises help you to train your attention.
In your daily life you will probably experience a stronger concentration and more peace of mind. In addition, you are probably more likely to end up in a state of “Flow”. Psychologists use the word “Flow” for the mental state associated with intense concentration. A relaxed alertness in which distractions disappear and activities seem to come naturally.
