Who am I? And who do I want to be? These 2 are loaded questions. However, you already know the answer, you just need to dig deep.
Grab a pen and paper, go to a space where you won't be interrupted and free of distractions. Take some deep breaths while thinking of the questions.

Read what you wrote and summarize your answers to the questions.
Now that you know, do you want to take the next step?
