Also, keep a record of your work environment and your productivity, try to identify associations, good or bad between the environment and your concentration. I made a list of things that help me concentrate that I can pull out when I'm having trouble concentrating. For example certain types of music help me immerse; having a clean (uncluttered) desk helps me. Before lunch is better than after lunch, etc. Remember your home office is not your office, and you will have to be disciplined to stay productive in the long term.
