SAGITTARIUS (Nov. 22-Dec. 21): Well-known actor James Caan has appeared in more than 80 movies, including notables like “The Godfather,” “A Bridge Too Far” and “Elf.” He’s also turned down major roles in some blockbusters: “Star Wars,” “Close Encounters of the Third Kind,” “One Flew Over the Cuckoo’s Nest,” “Kramer vs. Kramer,” “Blade Runner” and “Apocalypse Now.” His odd choices are a cautionary tale in the weeks ahead. Don’t sell yourself short. Don’t shrink from challenges. Even if you’ve accomplished a lot already, an invitation to a more complete form of success may be extended.
