Remember: It’s one thing to call yourself a writer; it’s quite another to actually write.
If you missed your word count, blew your scheduled time, and wrote a bunch of malarkey — but you still get to check “yes” — then consider the day a success. Get up tomorrow and do it again. The goal is to just get going and to get better and more consistent as we go. You can do this. Good luck. Remember: It’s one thing to call yourself a writer; it’s quite another to actually write. Do the latter.
