Someone is just about to walk into your office and ask you if you can do something that is both interesting and important. Unfortunately, it is slightly less important than the boring thing you are working on right now. Don't you wish you had already finished?

I have this on a post-it note, stuck to my monitor at work. Strangely, it is quite motivating at times.

Stop wasting my time! You should be working a lot harder, making lots of money and advancing in life. When you're me again, you can sit back and enjoy yourself.
