This could be a very important month in your work life. September starts with the life-giving Sun in your 10th House of Career, which tends to put you in the spotlight with added responsibilities. This transit in the precise and practical sign of Virgo rewards you for managing your job with a high degree of efficiency. Avoid temptations to stretch yourself too thin or to promise too much. It's better to be masterful in a small area than to be simply adequate across a wider swathe of responsibilities.
Cerebral Mercury is also in Virgo, where it challenges you to be as exacting as possible in what you say and do. Yes, it's possible that you feel that unreasonable demands are being put upon you. Yet as long as they're not blatantly abusive or illegal, it's smarter to buckle down and do the very best that you can.
Your expansive ruling planet Jupiter is triggered by Mercury and the Sun on September 7-8, which can increase your optimism and expand your vision of future possibilities. However, you might over-estimate a situation or be dealing with data that's not accurate. Just double-check your information before pushing bold ideas forward.
In fact, the New Moon in Virgo on September 15 is another signal to narrow your professional focus. This event in your 10th House of Career is useful for developing new skills or perfecting the ones you already have. Becoming more of an expert increases your capacity to fulfill your professional potential.
