Having an ideal schedule is also necessary for working from home success. Sticking to a schedule will add purpose and organization to your day. If you can, schedule your day around the time you feel most productive to do work. I personally am less productive in the morning, so I tend to work in the late afternoon.
It is also important to not expect yourself to be as productive as you were previously. Don’t feel bad if it takes you a couple of extra hours to finish a project or if you need to take a break away from work. Accounting for this change in productivity will help you control some of the stress you feel.
