You can save a lot of time not commuting to and from the office. By missing the traffic jams first thing in the morning and last thing at night you will be able to spend a lot more time with your children when it matters.
Working from home is definitely more cost effective. You save money on parking & fuel bills as well as having the luxury of rustling up a quick snack in your own kitchen. Forget about buying expensive tasteless sandwiches. Why not take the opportunity to learn some basic cooking skills and start eating well and feeding nutritious food to the children? If you have a headset you can still make & answer important business calls whilst cooking some delicious food.
Make sure that you have a decent dishwasher though. It is amazing how much mess you can make when cooking! Another idea is to get used to emptying the dish washer as soon as the washing cycle is finished. This means that you will always have a place to throw the dirty pots and pans in. Do not wait until it is absolutely full before you start the machine otherwise you will end up with dirty dishes in the sink.
So you have finally decided that you are fed up of boring office...
