I stopped doing this many years ago. And this is product of having an office badly designed or, your own home. When I did my home properly I just can't go outside to work. I cannot work better than the confort of my flat. I just go outside to enjoy, not to work.

My recomendations for a proper place to live, work and rest:

1. Decorate minimally your home. Use the furniture that you will use. Free all the space you can. 2. Choose a proper selection of colors and combine them well so you can achieve some sense of 'balance'. 3. It is important lighting: light it up all and well. Have choices like table lamps too for those moments you want dark mood. 4. User proper bedclothes, some people just use white beddings and the same ones at least for 3 months. Don't do this isn't confortable and nicer. Change it every week and it will help to improve the quality of the space. 5. Be clean. The more cleaner, the better you enjoy your place.

Following this you will never need to go outside for working. You will go outside just to enjoy a rest and fresh air not to bothering you with work again. Real disconnection.
