Monthly Horoscope for Aries

You'll be completely focused and determined to make your mark in the world this month in spite of any opposition or setbacks. You may be ruthless and too aggressive in trying to have your way. Tone it down a bit and you'll be more successful. Mercury in Sagittarius until January 8 will open your mind to new possibilities for the future. Uranus on the cusp of your sign will bring erratic behavior and the urge to totally reinvent yourself. This has been an influence for a while, but you may finally go for it and change things up.
