The big one would be "sincerity"

Lack of honesty, lack of commitment to your success. If you and your mentor are a bad match then its a big disadvantage.

Paid mentorship can be costly, potentially lacking in quality and leading to conflicts of interest. Depending solely on paid mentorship may foster dependence and limit one's perspective, as mentors may have biases and time constraints. Moreover, the transactional nature of paid mentorship might hinder the development of a genuine personal connection and lead to disappointment if expectations aren't met. Ultimately, while paid mentorship offers guidance, individuals should be cautious of its limitations and explore alternative mentorship avenues for a more well-rounded development.
