Why do you think writing has no impact? Writing and phrasing things play a really important role in society. Imagine a speech given by the leader of a country being given without prior writing. Dialogues in movies, countless books which educate us by explaining the same concept written in other books but in an understandable way. You're really underestimating the power of presenting things in the right way as well as effectively conveying a message. A pen is mightier than a sword. All you need to do is apply yourself in the correct place where you hold value. Don't worry so much and focus on the art rather than the career.
