How does the square between your Aries Sun and Cap Moon play out in your life?
That can be a difficult square to work through.
My Aunt had an exact square from her 10th house Aries Sun to her 7th house Cap Moon. It worked great for her because she ran her husband's business empire with an iron fist.
He had a trucking company. They leased big rigs to people. The clients paid their leases on time or she had those wheels repossessed quickly, no questions asked...She was a very lovely woman with great wit and charm. But don't cross her...
I had a young client with this same square and things were difficult for him. He has an Aries first House Sun, with Moon in 10th. Pisces rising...
He had a very controlling mother and continued that pattern with attracting controlling, bossy women in his relationships. He had a lot of insecurities and emotional issues but had the motivation and energy to work through them ambitiously.
He eventually became a Marriage/Family Therapist and was a very good one.
