Saturn shows you where your structure is missing. It's the experience of hitting the same limit over and over until you build the skill to pass it.
If your finances keep failing, Saturn is in your 2nd house. It will not let you move forward until you learn how to value your time and manage your resources with respect.
If your relationships keep stalling, Saturn is in your 7th house. It will not let you find peace until you learn how to set a boundary and keep a promise.
The struggle does not end when you finally break through. It ends when you finally build the competence that makes the struggle unnecessary.
