Embrace what fulfills you
Letting go of what makes you feel in control can feel scary. The question is, what are you trying to impact? Your happiness or your perceived level of certainty?
If we optimize for certainty, we will stick with what we know. If we optimize for fulfillment, we will learn to let go of what is heavy and draining and move towards what we truly love doing and contributes to others. We are designed to optimize for contentment, not certainty. We can know this because contentment feels better.
If you notice the fear of uncertainty has been holding you back, can you practice prioritizing something that you know fulfills you even a little bit more?
