If you have a home office, then it is important that you treat it like that. What I am trying to say is that many people forget that their home office is actually an office. It is a place of work and work performance decreases if you try to mix work with leisure. That is why watching TV while trying to work or having other distractions in your room is not a good idea. Makes sure that your room feels like an office. Make sure you have office furniture, no distractions around, and things that you may need for work like a PC or phone.
