Saturn in the 1st house

The 1st house is the self as others meet it. Saturn here makes that meeting careful. These people are often serious young and easier in themselves later, and they are read as reserved, capable or older than their years. Responsibility gets taken on early. The cost is self-consciousness: a critical inner eye on appearance and manner, and a caution that looks like coldness to anyone who has not been let in. Confidence here is built rather than given.
