What it is

A trine between Mercury and Mars

The trine

A trine runs in easy step — two drives in the same element, cooperating without being asked. The gift is fluency; the catch is that what comes easily rarely gets examined.

Mercury: mind

Mercury is your mind at work — how you think, talk, learn, and connect the dots.

Mars: drive

Mars is your engine — drive, desire, and the way you fight for and go after what you want.

The tell

How it shows up

  • You are quick, decisive, and good in a debate without being cruel.
  • You learn by doing and do by learning.
  • You get things done that other people are still discussing.

The hard part

The shadow

Named, not flattered

Impatience with deliberation. The ease can make you dismissive of slower, deeper thinking, including your own.

The move

What to do with it

Somewhere to go

Sit with one question a month without solving it. The trine is an executive mind; it benefits from one slow room.
