A user in noise.cash in the name of @BossLalang asked a question "How can you change the world with a pen?" A pen is a very powerful tool, you can make countries fight each other with the use of a pen. You can just right anything you want that can cause a good or bad result in your surroundings.
I've got and example. In our community we have comic book fans dc, marvel or any other comics. If you write something like DC is better than Marvel. You will witness a conflict between the fans of those two comic book that I stated.
So what if you right something about BLM, LGBTQ, TERRORISM or anything that is related to our society? That might change our surrounding. Even a tiny issue that is publish through papers, news, articles or other media, it can even make an agreement and dis agreement in our society.
Dr. Jose Rizal's work is a very good example of a pen changes the world. With the use of his pen he wrote the Noli Me Tangere and El Filibusterismo that criticizes the abuses and corruption perpetrated by the Spanish government during there time. With his work it changes the lives of Filipinos, he set the Filipinos free from the cruelty of the spaniards government.
To some up everything that has been stated so far, you can create or change the world with a pen by writing something you want to convey your message or write something you love.
