Keep a notepad handy everywhere to jot down ideas, whether for a new story, plot twist, or vivid description. When inspiration strikes, don’t ignore it. You might think you’ll never forget it, but often such things are quite elusive. Don’t take a chance on losing a true gem–write it down!
These also come in very handy if you get stuck at some point and need an infusion of creativity. For example, short story contests or opportunities to contribute to an anthology come along on a fairly regular basis. If you already have a list of ideas, it won’t be as difficult to come up with one when the opportunity arises.
