Is it possible to avoid unwanted thoughts?

After a breakup, you might think you’re fine until you drive by that one street corner, meet a mutual friend, or hear a certain love song on the radio. No matter how much you want to stop thinking about that person, everything is a reminder of the relationship. Aside from erasing entire chunks of your memory, á la Jim Carrey’s character in the movie Eternal Sunshine of the Spotless Mind, is it possible to banish unwanted thoughts?

The short answer is: maybe. But whether this makes sense in the long term is more complicated.
