Be wary of correlating productivity with either:
a) being in the office
b) being behind a computer
Here’s why.
You can, and should, only look at a screen for so long.
Work is not exclusive to being behind a screen.
Don’t feel guilty – as if you can’t be productive if you aren’t behind a screen.
You are not always most productive behind a screen – some of your best ideas come from being unplugged.
