What lights you up? If you are not sure, one way I have found to answer this question is to create pictures doing things that I love or would like to do. I have so much fun making these and think they also serve as a positive visualizations in daily life.
Since I began creating these pictures, I am more interested in my present surroundings. I look more deeply into things and get curious. What would I like to do in this situation? Then an answer comes and whether I am able to actually do what comes to mind or not, I feel a greater sense of wonder and interest.
There is also an instant happiness and connection with what is right in front of me. From this fun, simple, playful practice, I'm learning that it's not so much what I do in life but how deeply I enter into the moment and use the power of imagination to see possibilities.
If you are not sure what lights you up, I highly recommend any similar practice that gets you curious and creative in everyday moments.
