There are no connections, or aspects, between the Sun and other planets in your chart, which means you could feel quite a bit more independent than others around you. Your Sun Sign is your core self -- what makes you an individual, at a very basic level. The Sun directly influences your self-confidence and self-awareness, your strengths and ambitions and much, much more.
Without any other planets restraining your Sun, you can act as an independent agent, and establish yourself in the world according to your own will and effort. You may not connect with others very easily. Other areas of your life will take more focus and importance than the feeling of fitting in. You will have to learn to be friends with yourself first before relating effectively with others.
