“Work From Home” is terrible branding.
For some, this newer experience is black or white - I work from home OR I work from my office. As someone who has 'worked from home' for a long time, I have spent as much time working in coffee shops, office spaces, and random locations as I have in my own home.
A success tip I can offer you is to take the "location" out of the mix, and use this time as an opportunity to really think about where YOU are personally most productive. (Be honest with yourself, and with your boss, manager, or company.) Are you someone who thrives in an office environment? Are you someone who has learned that you are more productive being outside the office? Is a mix of those things perfect for your focus and mental well-being?
There is no one way to do it, but there is a way for you to do your best work - IF you pay attention and make some intentional choices.
Going forward, don't look at it as an either/or; look at it for what it actually is...an opportunity to be less stressed and more productive than you've ever been.
