why is seventh house shit? It's not, Saturn is fine with this house, it's the house of love and close friends, ruled by Venus. If Saturn doesn't have a mischievous aspect with another planet, this should be a friendly encounter.
Besides that, of course it's not the way that your birthchart dictates everything, it's your base constellation, so look at it as your source.
Saturn is often considered as an evil planet. That's bullshit, his lessons can be hard, but they're worth it! He brings strength and steadiness as rewards.
