I love the Work Awsome blog, and today they have a great article with 5 Tips to Successfully Work Outside the Office
One tip that is on every article about working from home ever written is to have a dedicated space to work:
This area should preferably be a dedicated office, but other areas can be used to so long as you have the space and privacy you need to work effectively. If there are other people at home while you work, consider playing some soft classical music that will drown out the noise they make but won’t be distracting to your work.
I find that playing some music on some decent noise cancelling headphones (like the ones you get for aeroplanes) does a great job of letting you zone out. Just remember to keep you phone in your line of sight below your monitor so you don’t miss any calls!
