Conventional and conservative, much of your energy is channelled into professional ambition and social advancement - you like to see practical results for your efforts and take pride in doing a job correctly. On occasion you can be calculating, selfish, materialistic and show a total disregard for others. Sexual relationships are not a priority - you can at times feel inhibited and clumsy in this department. However, if married, sex is elevated to the status of 'duty to perform . Lovemaking in usually conventional, controlled and unimaginative, but you do have your moments of transcendence.
Saturn in Capricorn

You should develop ambition, determination and a capacity for hard work in order to excel in business, politics or your chosen career. Your deep need for financial security and self-sufficiency will provide the necessary impetus for success
However, Because of these planets forming that Square Aspect with your moon, there is a very very strong chance that though you may end up being very good at your job, there will be a sense of not finding it as Emotionally appealing to your innerself as you may want to be.
I am puzzled a bit wiht your 'phraseology' ---"I've always thought it was a bit strange that half of my planets are in capricorn, and it travels together with venus, mars, and saturn everywhere"---
How do you mean "travels together everywhere?"
