I read blogs for a living

People say it takes twenty-one days from the time you begin until it has become a routine. Not "Learn C++ in 21 days" kind of thingy — more like get up every day at 6:30 AM (I usually get up around 9:00 AM), stop drinking coffee (I drink a lot of coffee), do 200 sit-ups before breakfast (no comment...), etc. Well, after given it very little thought, I've decided to put this myth to a test. I just need something to do, and that's where you come in: Give me something to do for twenty-one days.

I'll use my blog as a diary during the attempt and post a summary when I'm done. I'm very eager to get started as I have a lot of questions related to this... How long does it take to break a new routine? Will I notice a difference if I suddenly stop and don't do "it" anymore? Hopefully I'll be able to answer some when I'm done.

So, anyone got something for me?
