Mars in Taurus squares Jupiter (at 12 degrees Leo) today, creating some pushy, self-focused energy.
Mars in Taurus is actions that are focused on self-preservation, or creating something that's real. Those actions will be expanded by look-at-me Jupiter in Leo. Mars in Taurus can certainly use the push, because Jupiter will create dissatisfaction with the status quo (Jupiter is the rut-buster). This aspect can also create inspiration about how to get more (Jupiter) from what you have (Taurus).
Jupiter square Mars can result in exaggerated efforts, so there is a risk of pushing too hard, or taking on more than you can handle. The rush of enthusiasm that's created can steamroll others into compliance; this is not an aspect that invites compromise.
Overall, this is a nice build up to tomorrow's New Moon in Aries (ruled by Mars). Just remember that the transiting North Node is in Libra (which is about compromise).
You'll feel this square most strongly if you have natal/Progressed planets, angles or Nodes from 11 to 14 degrees of the Fixed signs.
