The existence of an idea is debatable, although the existence of an idea behind an action or inside a thing ... that's a given. Theories must represent how things work and how they are. In these first days of the Taurus solar journey, the material is what matters. Test your ideas by bringing them into being. Practical application is king.

ARIES (March 21-April 19). Good drivers don't accelerate while fixated on the rearview mirror. To avoid crashing into something ahead, look where you're going, not where you've been.

TAURUS (April 20-May 20). When it comes to certain subjects, you don't have to work at loving them. When you're engaged in their practice or study, you naturally radiate joy, as though this is what you were made for.

GEMINI (May 21-June 21). You're trying to accomplish something that requires you to dig deeper into your feelings, behaviors and thought processes. For this reason, ignore all things petty and shallow.

CANCER (June 22-July 22). Ironically, if you want peace, you'll have to fight for it. Start with building your defense and erecting protective guards around your peace so it's very difficult for anyone to rob you of it.

LEO (July 23-Aug. 22). A retreat isn't always fleeing the scene. It can be a strategic move away from potential trouble sources and toward your own essence. Any move toward balance is a move toward strength.

VIRGO (Aug. 23-Sept. 22). You've taken enough risks to know that if you risk in the same way many times, eventually, you will get comfortable with the very things that once frightened you. This is happening now.

LIBRA (Sept. 23-Oct. 23). You will wonder how much responsibility you should take for another person's emotions. It depends on what the relationship is. Think of your connection and responsibility levels as commensurate.

SCORPIO (Oct. 24-Nov. 21). Most emotional dynamics are not something to overcome but rather something to accept. It is futile to reject any feeling you're having. Just remember that you don't have to act on your feelings.

SAGITTARIUS (Nov. 22-Dec. 21). You want to make a decision based on your own values and metrics, and others want you to do what works for and pleases them. Do it your way, as a compromise will please no ne.

CAPRICORN (Dec. 22-Jan. 19). Everyone is different. You'd be surprised by where the discrepancies lie and how vast they can be. It's best not to assume that others know and understand what comes so easily to you.

AQUARIUS (Jan. 20-Feb. 18). You know what's at stake and are unsure of how willing you are to risk it. Should you lose, what's your backup plan? Gauge how eager you would be to follow that plan and you'll know your next move.

PISCES (Feb. 19-March 20). What goes disguised as a complex and nuanced problem is actually quite simple. It boils down to having the guts to do what falls in line with your own values, regardless of how acceptable that is to others.

TODAY'S BIRTHDAY (April 20). In the months to come, you'll become more accepting of your own impulses and trust yourself in a wider range of situations. You'll succeed beyond your own expectations at things you didn't even know you could do. You'll give support and love and have it in equal measure, although not always from the same people. Virgo and Sagittarius adore you. Your lucky numbers are: 20, 4, 10, 13 and 8.

ASTROLOGICAL QUESTION: "I'm an 18 year-old Virgo, and I'm not sure which way to go with my life. I could go to college. I could take a gap year. I could work and save money. I really don't know which is the best way to get my life going."

You are at the perfect juncture for some fun brainstorming sessions. Get out your notebook, and journal a list of things you want to accomplish in your lifetime. As a health-conscious and nurturing Virgo, your dream list should include how you want to look and feel, things you want to learn and relationships you want to have, among other things. Don't censor yourself. This is a fun trip through the land of imagination, and you don't have to think realistically.

Once you complete the lifetime list, narrow things down to a vision of yourself five years from now. Again, this is a fantasy, so stretch yourself, and let yourself include outcomes that are unlikely but very appealing.

Now, given your fantasies, what seems most pressing? Which life decisions could you make to line up with the version of you that feels most right? This exercise should bring you clarity, and you can begin organizing your plans accordingly.
