In an office, "work life" and "personal life" blend together - in watercooler chats, meetings, breaks, lunches, and happy hours. In remote, these two sides of life are more discrete. And that's a good thing.
Remote work doesn't signal the end of office friendships - it just asks you to be more intentional about socializing. In an office, socializing is automatic; in remote, undisturbed focus is.
But oddly enough, this focus can lead to the social bonds we all crave. Because when everyone's operating at their best professionally, it engenders mutual respect and admiration. Do great work, make great friends.
