As a rule, strong personalities tend to be less visible people in our society. Why? Yes, because they quietly and calmly do their job and communicate only with those who are interesting to them. They have neither the time nor the desire to waste their energy on meaningless actions, the purpose of which is only to attract the attention of others. Any attention.
They literally exude self-confidence and determination. Life has taught them never to give up and never back down, so don't expect them to crawl on your lap to give them a little of your attention.
However, this does not mean at all that all strong personalities are entirely reclusive loners. Despite the fact that they do not need someone else's attention, their charisma attracts those around them, like moths to a flame. They often associate with good and interesting people - not because they ask for it, but because such people like to be around them.
