Taking on a big personal project — writing a book, for example — can be daunting, especially if it’s something you’ve never done before. Instead of tackling it right away, it’s best to work your way up through smaller, more manageable projects that involve the same types of tasks as the larger project. For example, rather than writing a book manuscript, try writing a few short articles. Doing so will provide you with opportunities to hone your writing skills, get feedback, and learn how the publishing process works. These articles will essentially serve as a microcosm of the larger process, allowing you to refine your abilities when the stakes are lower. And you’ll equip yourself with the skills and mental prowess needed to tackle the more significant goal.
