According to Krumboltz, career concerns are least likely to arise from:

The reasoning behind this answer lies in understanding Krumboltz's theory of career development and the nature of career concerns. When individuals have too many goals, they may experience difficulty in deciding where to focus their energies, but this situation often does not create significant concerns related to their overall career direction or aspirations. Instead, it could provide opportunities for exploration and diversification.

In contrast, having no clear goal, feeling conflicted between equally appealing options, or expressing worries about aiming too high can prompt significant career-related anxiety and uncertainty. The absence of a goal can leave individuals feeling lost, while high aspirations may generate fears of inadequacy or failure. Conflicts between equally attractive alternatives can cause stress and indecision, leading to heightened concern over making the 'right' choice. Thus, it is the presence of numerous goals that is least likely to give rise to career concerns when evaluated alongside the other scenarios mentioned.
