When you are working from home, either for a few days or always, there are a few things you might need to do to help keep you focused and productive.
Best Place - First, you need the best place to work. Have a designated room, if possible, or space that is for working only. Keep this space like it is sacred space. Don't put things in that room/space that are not work related (desk clutter can suck time away trying to sort through what you do and don't need), and don't use it as a hang out area for other things. When you enter your "work" area, your brain will think WORK if you keep it that way. If it is a space that you use for all sorts of things that are NOT work related, then your brain will think of those things when it should be concentrating on working. This is why a kitchen or dining room table is not a good permanent solution for working at home!
Best Time - What time of day are you most productive and can get the most amount of work done? Once you know this answer, stick to that same time of day EVERY DAY. When you are in the habit of being ready and in your space at the same time every day, you will be more focused and productive. It's the same when you are NOT at your best. Don't push in more time in your home office if you aren't in a place to be focused and working. Less mistakes will be made this way and it's better for your health to make sure you don't work too much as well.
Best Boundaries - You need to set up some boundaries with your family and friends. Let them know the times you are working and when it's a good time for them to call or when you are available for things. This will help make less interruptions when you are working. Some will still happen, but, those who know the boundaries, will generally stick to them.
Best Background - While you are working, it might also be a good idea to invest in some good headphones or earbuds so you can drown out background noises (if you have a lot) or listen to motivating music. Also, it might be a good idea to turn off your ringer on your phone or shut off your email or social media for a time during the day so you can be focused for the really important things.
Best Breaks - Another thing that will help keep you focused and productive are GOOD BREAKS. If you have no one to tell you "it's break time" you will need to remind yourself to get up and walk around for a bit. It can renew your energy and make you more attentive when you go back to your desks too. Plus, then if there are any pressing family situations or a friend you need to call back, you can deal with those things too and get them off your mind!
