If I have a meeting first thing in the morning that’s when I’ll get there. Even if it’s at 10.

I never manage to absorb anything in a pre-0900 meeting. That first chunk of the day is for me to catch up on all the shit that happened since I was last there (personal opinion).

Showing up early or on time for any meeting, other than a client or outside collaborator , communicates to everyone involved that you have nothing better to do with your time.
