The house of saturn is a learning ground and one in which one has a weakness. person with saturn there might not be able to fulfill their ambitions, not know what their life calling is, always feel failure until successful, saturn is also the treasure one finds eventually after hard work, 10th is saturns natural house so not all bad, i would say to anyone with it, keep at it, perserverance brings rewards
Just my two cents
eta the irony about saturn anywhere is that the person is potentially brilliant at it but takes them hard work or years to express or maintain it
i have saturn in 5th house, i envy celebrities and normal people who just love their lives and live them with gusto and wonder why i cant and haveno idea what stops me, saturns a mysyery sometimes
perhaps saturn via house shows you what you should be striving for and kick against what holds you back? As a testand strengthening of your character
