No, having a common strength or weakness is not necessarily bad. Depending on the situation and context, it can be beneficial for people to share similar strengths in order to work together more effectively.
It can also help individuals recognize their weaknesses so they know what areas of improvement are necessary.
Having a shared understanding of strengths and weaknesses among group members may lead to increased collaboration within teams as well as better problem-solving skills when faced with challenging tasks.
Additionally, being aware of both your own personal qualities along with those found in others allows us to build stronger relationships that foster mutual growth and respect between all involved parties.
