While I’d like to write every day, some days are significantly more difficult. Whether it’s stress or something more traumatic, there undoubtedly will be days where you really feel like you can’t possibly write anything- let alone anything you’d want to read again later and work on. On those days, maybe you don’t want to write, and that’s okay. It’s best to remember that there are other ways to still actively work on your project while not actually writing. 

• Like editing. Someone once told me that it’s easy to write in a good mood, it’s easy to edit in a bad mood. It’s true. When you’re upset, you’re more critical. You think everything is terrible – you might need to tone it down a little to edit effectively. Avoid big picture edits, look at small scenes and try to figure out how you can improve them. Are there better words you could be using? 
• Or do research! So say, your story is set somewhere you haven’t really been to all that much. Time to look it up. Google search is your new best friend. You could find picture of the setting or clothes or whatever and make a mood board. The point is that you’re still actively thinking about your project in a way that your mood is not going to hold you back. You might even feel better in the process.
• Plan. So if you like what you’ve already written (or you liked it when you were in better spirits) plan ahead. Start thinking about where the plot is going. Consider how every character plays a role. (Remember minor characters do not think of themselves as minor characters – that is always where I start, because my first drafts are riddled with characters I’ve forgotten about.)
