The Sun moves into Pisces today, adding more fuel to the Pisces stellium.
Transits of the Sun are a less specific type of energy than other planets. The Sun acts as an accelerant (or a trigger) drawing your attention to the part of your chart that it's activating. So if you haven't felt much from the Pisces stellium, that may change now, or when the Sun passes over Neptune on February 21st. Or when it hits Chiron on February 27th, or Mercury on March 4th.
It's easy to lose yourself (your focus, or your purpose) with all this Pisces. So ask yourself this question: what is my purpose? The Sun represents your life's purpose (and your ego) in the natal chart. When you start to lose sight of what that is, it's a signal that you've drifted off course, or the course needs to be changed completely.
If your birthday is between today and March 20th, there will be a massive concentration of energy in one area of your Solar Return chart. This will dominate your year ahead, so it might be an idea to figure out where that energy will hit.
