Mercury Trine Saturn:

You possess excellent powers of concentration, and enjoy studying or deep thinking in solitude. Discriminating and highly rational, you get right down to the bare bones in any discussion, and are quick to see the fuzzy thinking or weaknesses in another's logic. You are well-suited to any work which requires organized thinking, precision, and a methodical approach. You enjoy working on problems that others consider too tedious, repetitive, or technical. You tend to become a specialist in some field of knowledge, and to become engrossed in all of the small details of that area, sometimes not realizing that few people share your particular interest, especially to the extent that you do.
