When you’re improving your craft, there is no other task than to perform the work. There is no checklist or to-do list. There is no project management to becoming a better writer. You may use tools to help you progress, but the primary activity is always to write. I see that you’ve done what you needed to do for the week. Your assignment is done—why, then, do you look around like you have nothing to do? Did you think writing stops there? When your self-assigned work is finished? Assign yourself more! Don’t stop at this week; finish next week, too. Get ahead. Start a new project. It can be short, but it must be a project in which you’re able to practice your craft. It doesn’t matter if it’s directly useful to your website or for anyone to read. What matters is that you’re writing and improving your ability to create.
