I know it's a small thing, but your choice in writing implements can say a lot about you. Do you carry a simple plastic tube with cheap ink, or do you hold a solid, well-made piece that makes an impression? Or do you not carry anything at all? A pen holds stories and signatures, words and dreams, and you can make one that leaves an impression every time you put some words to that page.
That's why you should carry something impressive, and why you definitely should make your own.
