Step #1: Write a bunch of emails for work ... especially ones to your boss
Step #2: Save emails as "drafts"
Step #3: At approx 7 PM change the time zone on your email to be on Hawaii time, and hit "send" on all.
(This should time stamp all of your emails for approx 3 AM).
Step #4: Tell your boss how you were up all night working. Throw in terms such as 'dedicated', 'committed'.
*This trick works best if you don't live in Hawaii
