For me, it cycles through the challenge of writing while in classes to the wide open space of vacations and summers when I should be writing, but seem to do every other thing on my to do list before sitting down at my computer.
Over the past few years, I've stumbled across some great writing resources, many provide subscription emails. A few subject lines from these resources popped out at me this morning from my inbox, and I'd like to share.
Much of Henneke's emails focus on marketing strategies. But she also provides writing exercises throughout her series that help you mold your writing into something more concise, and pointed.
My Favorites from Henneke:

Karen's blog has some great posts about a variety of PhD topics. She also offers a writing accountability program, Unstuck: The Art of Productivity, that you can register for (small fee).
I highly recommend her book, The Professor Is In. Add it to your bookshelf or your kindle.
