Deeply disagree with this. You don't have to approach writing from the standpoint of "my thoughts are so important." 

Writing and communication is one of the greatest art forms in existence. When properly utilized, they can invoke great emotion in the reader from peace and happiness to anger and hatred. 

Writing is also an extremely cathartic exercise.
