● A separate office area is a must so you can concentrate on work.
● A good phone with handsfree. There are conference calls and not having to hold/cradle the phone is a must.
● A good network setup. I have a router where I can set up multiple SSID. I have one for work and only work. Nothing else in the home network can see that. It also helps to have decent high-speed internet.
● A comfortable chair. If you work all day then a comfortable chair is a must.
● A proper desk with keyboard tray. It helps having the keyboard (and mouse) at the right height so your hands, wrists and arms aren't stressed.
● Taking regular breaks. Get up, walk at least a few minutes every 20-30.
● Have your lunch outside of your 'office'. Take a break away from work and unwind.
● At the end of day shut it all down. Take 'me' time away from work.
