First thing I would do when I got to the office
You don't have to but it would pay off in the long run. At least I think so.
I would walk around greet everyone in the office. A quick hello and fist bump. That's all. 15 to 30 secs per person.
I would do this even on the days I didn't feel like it.
As they say, "team work makes the dream work."
I wrote this on my IPhone 7 Plus real quick before jumping into the shower and took the photo earlier today while working at a friend's office.
