Sometimes people will comment on an artist's drawing asking what pen the artist used. Then hot shots on the Internet are like "ugh why do people ask which pen—it's the artist that makes it good." While the artist is absolutely the main reason, the tool plays a huge role. Here I've drawn the word “COOL” at the same size with 8 different pens/markers to illustrate that point.
Keep asking which pen. Keep trying new pens. It's your life.
