All outward appearances and actions are driven by core values, not the works themselves. Nobody gives to charity because charity in and of itself is positive. Charity is just an outward reflection of a core value that calls on people to give and be gracious toward others.
As you look at your actions and what you enjoy doing now, you should inquire about the values that drive that behavior. Do you write because you value ideas, or do you write so you can share your thoughts? Or does something else drive you? Of the things you’re interested in, what is the underlying value that drives your interest in them? Understand how you are pushed and pulled in different directions, and you will be better able to stick to your values and improve them along the way.
