After 6 months working from home I decided to rent an office space.
Turned out to be a really good decision for me and it helps with some of these issues you are describing.

I rented a small space with two other people (doing their own business).
It´s great to have someone to talk to during the day and we help each other with good routines. Especially when it comes to food! :) I´d eat out/snack all the time if it werent for them. Now instead we eat together, usually healthy stuff.

Thanks for a great post!
