I took my kids out shopping the other day to pick some things up. While we were out, one of the kids started playing one of the demonstration video games in the store. They hadn't played the game before, and weren't really all that concerned about place or position - they just knew they were having fun.
While playing the racing game on the demonstration system, they were driving around what appeared to be a mostly-deserted track. I knew from experience that it wasn't, and I noticed immediately the indicator that showed them in 8th of 8 places. They didn't seem to notice, or care, and it made me reflect.
How do you know when you're leading?
How do you know you're not behind the curve, and just can't see the first place car?
