What does it mean to know exactly what you are here to do, to create? To know in your heart who you are becoming is fulfilling the essence of who you are meant to be.
Just for a moment sit with the possibility of realizing all that you wish for arriving to you in perfect divine alignment.
Sitting still is a great thing to do anyway, but particularly if you are discerning which path, pursuit, endeavor to engage in further. Sit with it, tune into your heart place your hand on your heart if you wish, and ask.
Now listen as deeply as you can. Wait, it will come, some kind of something will come to you around the issue, the decision, the choice. If in doubt of what you are shown, ask again, take your time, because not taking your time is far more expensive in all regards.
Another way is to hold several possible choices out in front of you sort of arrayed on the table you might say, and see which is brightest, which holds the most pull for you. You can hold up each one and consider it and then place it down again and see what you see. The main thing is to recognize the connection between the desire for what you are hoping such and such will deliver and the energetic match with what that thing is in reality.
Your body holds enormous wisdom and can give you amazing clues sometimes in not so subtle ways of which path, choice, person, idea is in accord most with who you are and your path and which is not. Generally, expansion and a feeling of ease is a sign of go. Similarly a feeling of constriction, or holding is a sign of no or at least not right now. Generally speaking to be used as a guideline.
The truth is only you truly know for sure.
