Which of the following is NOT cited as a common obstacle to achievement?

Setting goals that are aggressive, while potentially challenging, is not typically cited as a common obstacle to achievement. Instead, it can often serve as a motivating factor, pushing individuals to stretch their abilities and reach for higher levels of performance. When individuals set ambitious yet attainable goals, they may be driven to improve and achieve more than they initially thought possible.

In contrast, failing to set specific goals can lead to a lack of direction and clarity, making it difficult for individuals to work towards their objectives. Similarly, setting too many goals too soon can lead to overwhelm, diminishing the likelihood of success in any one area. Lastly, the failure to adjust goals in response to changing circumstances can result in frustration and a sense of stagnation, as individuals may find themselves working towards targets that are no longer relevant or attainable. Thus, aggressive goal setting is not generally viewed as a barrier but rather as a potential means to stimulate growth and achievement.
