Life is precious. Enjoy it.
If you’re five minute late for dinner, maybe your friends got there on time and your table is just waiting for you, maybe if you’re even more late, appetizers will already be there!
If you’re five minutes late to a meeting everyone will look at you funny in the beginning, but then they will assume you spent the rest of the meeting trying to catch up on the info, and wont ask you any questions.
Of course, lets be honest, usually I am the one who is five minutes late, but is also five minutes earlier than everyone else, so usually I am the one saving the tables
