You are satisfied with yourself and the goals you hope to realize. You won't adapt easily to changes in your life, unless you sense these changes are in your best interest. You stay clear of the business of others and expect the same from them. You are highly motivated to achieve your agenda, focusing well on objectives, and normally gaining successful results. Even if you don't succeed in the eyes of others, you are self-satisfied with your accomplishments.

Sun conjunct Mercury
