Sun square Mars in the natal chart creates a very tense energy inside which looks for expression through some kind of action, sport, sex, creative self-expression. These people need to be doing something all the time. The square causes obstacles in self-assertion which have to be overcome with the courage and fighting spirit which comes naturally.
On the negative side this can lead to setbacks, frustration and may boil over as arguments, fights or tantrums. Once the energy finds a safe way of expression, then the tremendous energy can lead to great achievements in Mars activities such as sport, military endeavors, fighting for a particular cause, even dramatic acting. The fiery willpower really does need a useful outlet to stop this warlike energy turning on the self or loved ones. Competing and winning is important to maintain a healthy ego.

Sun Square Mars Celebrities
Stacy Keach (12′) is a great example of turning setback into achievements. Born with a cleft lip he underwent many operations as a child leaving scars both physically and to his ego. Through his long acting career he usually wore a moustache to hide the scars. Now he has turned to energy out as a fighter. As honorary chair of the Cleft Palate Foundation he fights to get insurance coverage for people to have the corrective surgery. Earlier in his career, Stacy caused harm to himself and his loved ones through drug abuse and ended up in prison. Again he turned this setback into something useful by fighting back and winning, starting an anti-drug crusade once he was released.
Another celebrity with Sun square Mars is Tina Turner (47′), who had many obstacles to success. Beaten by her husband for 16 years before she bailed out alone and broke. Other fighters include prolific writer and co-founder of the Lesbian Avengers political group, Sarah Schulman (36′); Military major and politician Jack Marshall (15′); and Lucille Ball (50′) nicknamed “Tessie Technicolor for her flaming red dyed hair”.
