With the exception of Marty McFly, Dr. Who and a few others, we in this existence are experiencing time as an arrow that flies ever-forward. Things do not, as a rule, go back to the way they were. As Mercury pulls away from Saturn, aka “Father Time,” we are reminded that even when you clear, clean and reset, hundreds of slight alterations add up to an entirely different situation.

ARIES (March 21-April 19). The question of when to stop is bound to arise. “Quit while you’re ahead” is the saying, but how far ahead? If you pull back too soon, you’ll never discover the true limits of what’s possible.

TAURUS (April 20-May 20). You have many ways of keeping the kingdom of your own mind in a beautiful balance. However, you could still use a few more tools and strategies to keep trouble out and a lovely peace within. You’ll pick one up today.

GEMINI (May 21-June 21). You’re preparing for something important, and mindset will make the event a winner. The right ritual will help you get into the spirit of this. Take an experimental approach to find what works best for you.

CANCER (June 22-July 22). Change in any direction because they all go to the same place today. You’re like the water of your sign. Water always finds the way. Whether you fall soft as rain or crash like a mighty wave, you’ll eventually be at the sea.

LEO (July 23-Aug. 22). When you’re displeased with what you get, you usually adjust what you give. Today, you’re not so sure. It seems like the unpreferred result is a fluke. If you don’t change a thing except in the timing it takes to try again, things improve.

VIRGO (Aug. 23-Sept. 22). Broaden your scope and stay aware of a wider array of options because it’s the ideas on the outer edge that have the potential to really delight you. You’ll be offered something unique and you’ll be in just the position to run with it.

LIBRA (Sept. 23-Oct. 23). The road that feels right for you will actually be right. Unfortunately, it won’t be the shortcut. That easy road would get you to the destination, but without the requisite skills to be as effective as you want to be upon arrival.

SCORPIO (Oct. 24-Nov. 21). It seems like it should be easy to get to know people, but it’s a little trickier than it seems sometimes and requires curiosity, awareness and the ability to retain and correlate the information you glean. Today, it’s a bit of a project, really.

SAGITTARIUS (Nov. 22-Dec. 21). As much as you try to make sense of contradictions and inconsistencies, it’s not always possible. To accept the disparate pieces of reality without attempting to close the gaps will bring deep peace.

CAPRICORN (Dec. 22-Jan. 19). The invitation seems casual enough, but it holds the key to a transformative opportunity. This is the gateway to a new and significant chapter. With a little preparation, you’ll enter with grace and intention.

AQUARIUS (Jan. 20-Feb. 18). A dream can never be fully finished, as it keeps dreaming itself into the unreachable horizon. If you’re satisfied and want to flit like a butterfly to the next dream, it will be waiting for you like an open blossom.

PISCES (Feb. 19-March 20). It’s not the win or the loss that makes a champion; it’s the heart you put into the game. Today’s plays will include pushing forward as a team, regrouping to fortify one another and taking a few crucial shots, too.

TODAY’S BIRTHDAY (Sept. 18). The hand of destiny guides you to the most auspicious path, and you’ll finally either gain the position you’ve been working toward or accept one that was unknown to you, though a vast improvement, nonetheless. More highlights: Help with admin and adulting so you can have more fun, a conflict resolved, and several small plans converging into a huge deal. Gemini and Capricorn adore you. Your lucky numbers are: 2, 24, 3, 14 and 6.

CELEBRITY PROFILES: Known for efficiency, productivity and work ethic, Virgos can keep several plates spinning at the same time. As though to prove the point, actor, director, writer and cocktail entrepreneur Aisha Tyler has over 70 roles in her filmography from “Friends” to “Criminal Minds” and “The Talk.” Tyler, who comes from the world of stand-up comedy, was born under three sharp-edged Scorpio planets and four hardworking Virgo planets. Moon and Saturn in Taurus indicate determination.
