They say nothing's certain except death and taxes, so be prepared to pull out a backup plan today. An unexpected cancellation could put an end to an arrangement you've been counting on for a while. This is good news, though. Any alterations you make will help you move in a more active, positive direction. This feeling that anything is possible at any moment will continue for a while, and it will keep you on your toes. This is a good exercise for your brain!
