a few weeks ago, one of my friends basically said "jonas, I received an invitation to submit something to conference X but I'm too lazy to do it and also the conference isn't advanced enough for my high level of research*, why don't you write something? Oh by the way, the deadline is in two weeks. Enjoy!" so I got two 80 hour weeks out of that kind offer. (*of course he didn't say those parts, but it's a better story this way)
