I get a kick out of this because I think it describes me well.
Capricorns are thought to be loyal, ambitious, dedicated, focused, honest, disciplined, patient, hard-working, kind, generous, supportive, dependable, tolerant, attentive, and a serious character. But the Capricorn is prone to coldness, aloofness, lack of emotional tolerance, materialistic, vindictive, bitter, and melancholy.
Capricorn is one of the most stable and (mostly) serious of the zodiacal types. These independent, rocklike characters have many sterling qualities. They are normally confident, strong willed and calm. These hardworking, unemotional, shrewd, practical, responsible, persevering, and cautious to the extreme persons, are capable of persisting for as long as is necessary to accomplish a goal they have set for themselves. They are reliable workers in almost any profession they undertake. They are the major finishers of most projects started by the 'pioneering' signs; with firm stick-to-it-ness they quickly become the backbone of any company they work for.
Capricorns make resourceful, determined managers; setting high standards for themselves and others. They strive always for honesty in their criticism of self. In their methodical, tough, stubborn, unyielding way, they persist against personal hardship, putting their families and/or their work before their own needs and welfare to reach their objectives long after others have given up and fallen by the wayside. In fact when practical ability allied with the drive of ambition are required in employees to make a project succeed, Capricorns are the people to hire. They plan carefully to fulfill their ambitions (which often include becoming wealthy), they are economical without meanness, and able to achieve great results with minimum effort and expense.
Their intellects are sometimes very subtle. They think profoundly and deeply, throughly exploring all possibilities before deciding on a 'safe' alternative. They have an insatiable yet methodical desire for knowledge. They are rational, logical and clearheaded, have good concentration, delight in debate in which they can show off their cleverness by luring their adversaries into traps and confounding them with logic.
Their occupations can include most professions that have to do with math or money and they are strongly attracted to music.
