Eventually, we will find ourselves on the road. Some of us will do it more frequently than others, but once we are away from our home base, we all feel that same sense of estrangement.
We can't do things as quickly or as effectively as we can where we have our perfect set-up. Sometimes all we can do is take little notes and save them for later.
It is frustrating to not have your home base with you. It is frustrating to only be able to take little notes. But do take those notes. They still allow you to be actively productive while you're out there.
