It is hard to say. A lot of actors' horoscopes are available on line at
www.astro.com on the Astro-DataBank. They are really are all over the place!
What sort of acting experience do you have to date: high school plays, for example? Local community or children's theatre? Are you enrolled in or interested in attending a college or university where you could major in theatre, try out for plays, and do workshops where you would get coaching and feedback?
Acting is a highly competitive field. How would you rate your motivation in the face of rejection? Can you bounce back and keep on trying? Are you a good "people person"? A big help in this field is the ability to connect with senior people who are already well situated as directors, producers, casting directors, and so on. Then is your primary interest film, TV, or the stage? Can you sing or dance, as well?
If you can't answer any of these questions, it is either time to start moving, or else to consider how serious you really are.
