"‪Achievement‬ ‪‎motivation‬ refers to a desire for ‪excellence‬ (as individually or personally based rather than socially or interpersonally rooted). It is closely linked with an individual's tendency to push him- or herself ahead and ‪actively‬ strive for and ‪seek‬ indiviual ‪successes‬." (Atkinson, 1964; McClelland, 1961)
