Of course, the best way to avoid spoilers is to stop going to places where they live. Despite trying to hide from any piece of Star Wars information, I'm still going on Facebook, Twitter, CNN, and other general sites fairly regularly throughout the day. If I really really wanted to commit to being spoiler-free, I'd have to make a change in my habit. Sadly, as much as I want to be surprised tomorrow night, I'm willing to risk accidentally reading something so I can continue my typical internet routine until then.
This, of course, is nothing unique to me; it's something I see with students, co-workers, and everyone all the time. There's a difference between "trying" for something and actually making the changes necessary to make them happen. Sometimes my students will "try" to get a good grade, yet they won't do any work at home, or make up assignments. Co-workers will "try" a new piece of technology but quit after the first hiccup...or try to make it fit their old model. Even me, I'll "try" to make my class more engaging...but sometimes I still do the same thing as the year before while hoping for a new result. "Trying" without changing is like hoping to avoid spoilers, while still looking for them in plain sight. Or as Yoda would say "try not. Do, or do not."
