Amateurs learn the basic moves of the skill—whether golf, chess, or, presumably, mindfulness and the like—and very often level off after about fifty hours of improving through practice. For the rest of the time their skill level stays about the same—further practice does not lead to great improvements. Experts, on the other hand, practice differently. They do intensive sessions under the watchful eye of a coach, who suggests to them what to work on next to get even better. This leads to a continuous learning curve with steady improvements.
