Was able to write 1.5K words through the barking of dogs and interruptions and anxiety over being late for the train. It's all about getting rid of the fear. It doesn't matter where you write or for how long, what matters is getting over this terror that you will suck. Once that's gone, all is gravy, and traveling is teaching me this lesson. It's fantastic.
Now I'm back on the train and have 500 more words to write to finish this chapter. Onward.
