If your Mars is in Scorpio
When you want something, you get quiet and focused. You can stick with a goal for months, figure out what other people are up to, and wait for the right moment instead of rushing it. Your desires run deep, and you keep them private. A betrayal can stay with you for years, and your anger tends to burn slowly rather than flare. Dropping an old grudge frees up energy for what you still want.
Don't know your Mars sign? In most cases, your birth date is all you need to look it up.
