What is the number #1 challenge with remote work?
We have not figured out how to deal with ourselves.
In an office environment, a lot of structure is provided for you. You are told exactly when to show up and when to leave. You are told exactly when to go to eat. You get social interactions with co-workers, and these social rules of engagement are understood.
In a remote company, the structure does not exists. You have to build it from scratch.
