March 23 in profile
Early Aries is the sign in its purest form, and two degrees in there is still nothing worn about it. The decan is Aries again, Mars again, which gives a single-minded drive and a strong sense of self. A March 23 Aries wakes up ready, says what they think and treats obstacles as invitations. The newness of the degree shows in their enthusiasm: a fresh idea lights them up completely, and they want to start before lunch.
They help fast and physically. Someone needs a sofa carried, a flat painted or a lift to the airport at 5am, and they are already reaching for the keys. Generosity is straightforward and immediate, without much ceremony. What they find harder is the slow kind of support, listening to the same problem a third time. A short note in the diary to check back on a friend makes their help last beyond the rescue.
Romance, for them, is a chase. Attraction is instant and obvious, and they enjoy the pursuit as much as the result. Playful competition, a race to the top of a hill or a sharp debate, works as flirting. Once committed they are loyal and protective, though they can lose interest if things become too predictable. Planning small surprises, a new place every month, keeps alive the spark that matters so much to them.
