I am assuming you've read the previous articles on energy, elements, and the elemental triplicities. If you haven't, I recommend starting there and coming back.
Cardinal fire, aries is the most active and forward-moving of fire signs. It is first among all zodiac signs, and is the exact kind of energy you need to deal with pushy people, job interviews, bullies, and wild animals. Aries bypasses fear, anxiety, and thought paralysis.
You might have heard the quote "put your own oxygen mask on, first, before you help others". Aries will put on its own oxygen mask, but not because doing so will make them more useful to others. Aries believes unquestionably in its own right to exist. Aries energy won't politely wait on a conveyor belt to be slaughtered. It'll raise hell to seize the miniscule chance of escape by the throat. Aries does not question the odds or ask whether victory is even possible. It's too busy fighting. Survival is the strongest impulses, and challenging survival puts the ram's back against a wall, preparing it to fight for its life.
Sure, Aries will fight when threatened. But there's another kind of fight it has. The same moral relativity that drives Aries to put on its oxygen mask first drives it to compete. Aries might end up a loser, but not without a fight. If there's 12 lunches and 13 people, Aries will ensure it isn't the one skipping out. Aries will explain why it is the best candidate for a job position, and mean it. In basketball, there's a brief moment when two players are holding the same ball. Aries will pull with its entire strength to retrieve that ball. It's not an issue of survival. Aries doesn't just want to win, but its wants to fight. There is a state of excellence reached when an individual pushes themself to their limits moving towards a goal. This is Aries sparring, scrimmaging, and conducting war games. While certain egos can stand to be a big fish in a small pond, this leads to a stagnation that Aries cannot abide. This embodies the expansive nature of fire. This can often look like a friendly form of competition where Aries pushes themself and those around them to compete in a low stakes forms where the main goal is the practice.
The most abstract notion of Aries is dignity. This is not to be confused with pride, but instead with a strong self-concept. Charged with Aries energy, a trans woman knows she is a woman. Neither does she have to prove this to anyone, nor does she need to engage civily with those who would destroy her identity for the sake of social games. "I am who I am" is a statement made in confidence and without reservation. Aries energy often sees loved ones and occasionally complete strangers as an extension of themself. This might look like "if you want to get to them, you'll have to go through me, first". it might look like "Don't mess with MY loved one!" It might look like challenging a bully to protect their victim, even if that bully is bigger, stronger, or has legal or social leverage over Aries. Aries would gladly die on its feet as the person they are, rather than live on its knees as the person someone else wants them to be.
Music is my first recommendation. Listen to music, get pumped up, and put on your war face. Songs like this, this, this, this, this, this, this, and this. The lyrics aren't as important as the emotions they elicit. Visualizing yourself boxing, racing, or competing in various sports can help. Physical activity may help. Additionally, entering a fight response. Some phrases:
