Inquisitive and independent by nature, Sagittarius natives always want to keep their options open to preserve their freedom.
It's not that you can't commit to a person, job or idea, because once you are really into someone or something, you are loyal and devoted. You are a truth-seeker and just want to make sure it's the right one before settling down.
