Work With What You Have.
Don’t worry if you don’t have a spare room to turn into a home office, this just gives you a chance to get creative. Pick a place that you can mark as yours and make it functional and comfortable. Try turning your couch into the most comfortable "office chair" you've ever had, or try adding scented candles, Bossanova music, and cute office supplies. Whatever your taste, go all out and make it a place you'd happily want to spend 8 hours in.
Act Like You're Leaving The House
That means actually showering and shaving on a daily basis. Just because you're working from home doesn't mean that you should roll out of bed only 2 minutes before your official clock in time. Get up, and put on pants for goodness sake. This tells your brain that you are now in "work" mode and will make it easier to concentrate throughout the day. Try giving yourself something to look forward to 30 minutes before you start your workday. You can experiment with different clothes to wear, songs to wake up to, or maybe quiet is what you need the most. Play around with different ideas and see what you can come up with to make your morning as fun or as zen as you want, then watch your productivity soar.
Set Clear Expectations
Many of us are working from home with the added pressure of children, and it can be hard for them to understand that they cannot have complete access to you every moment you are home. This will take some strategy and planning, but setting boundaries will allow you to work in peace and get important things done. Letting those around you know your working hours and availability and not allowing total access to you for a few hours will pay off, in the long run.
