Are you? People rarely use that phrase if they aren’t. Why go out of your way to pretend when you can just state your name and occupation?
“Happy to be here” means you got the joke. You realize it’s a privilege. That the connection is not guaranteed. When you do an interview, are you happy to be there? Do you look forward to the meeting? What about the group assignment discussions? In the realization lies the choice.
Everyone who’s happy to be here remembers a place where they weren’t. They thought it was the wrong crowd, the wrong date, the wrong company they interviewed for. Until, one day, they chose to be happy to show up for the people right in front of them.
