How long does it take to break a habit?

I know I should change. There’s a better way. There’s a search engine that doesn’t support a different company. There’s a search engine that actually gives a better user experience. There’s a search that needs my help (and everyone’s) if it doesn’t actually give you an answer and not just a bunch of links.

Today, after all these months (years?) of chiding from coworkers and peers, I am going to break my Google habit. I will use MSN Search exclusively. I am going to actually send feedback if I don’t get the results that I want.

So help me, I am going to put an entry in my content advisor to block the site if I slip up and type in the address of the wrong search engine.

How long does it take to break a habit? I’ve heard 10 days. Wish me luck.
