I think taking time to reflect on the progress you made in the last week/month can be good to keep you from burning out. That or finding someone who has a mastery of what you're learning and just talking with them about what you have been doing. Both of those helped me get through learning programming for the first time.
Try to have a goal you want to accomplish. For example, while I was still learning to program, my goal was to make something like the ones you would find on chrome experiments. Having a goal not only gives you direction, it gives you something to look forward to.
Change your expectations from short term to long term.
Try and visualize how your life will be improved after you've invested in learning over a period of time.
