I have always loved writing devices. A pencil with an eraser cap is typically behind my ear.
I have mechanical and graphic pencils always around and always in use. I also have an electric pencil sharpener on my desk. As an engineer, I take copious notes everyday.
Writing music, stories or poetry I use a pencil.
Other uses: Sketching, working with wood, grocery lists.
You will make mistakes along the way. But you can correct them and learn from them. Mistakes, and failures, are not fatal.
