For those of you that work in an office, you know that around 3pm you start getting just a bit tired. So what to do? Another cup of coffee or get more rest at night? Nope, take a 20 minute nap.

My suggestion is that you get more sleep at night, drink a ridiculous amount of coffee in the morning and then sleep through afternoon meetings.
