Over at CSS Tricks, Sarah Drasner has a nice article going over some productivity tips (in particular if you’re the type of person who likes to have a lot of projects happening at once). For instance:
Push outside of your comfort zone, but slowly
Work on a few things that you know and understand, and a few things you don’t. We should foster personal growth in our projects, but without some semblance of comfort, it’s easy to get discouraged. Let your projects push the limits of your boundaries, but don’t go overboard. Give yourself a foundation to spring off before floating into space.
