Depressed, am I stupid?

Hehe, nothing. When I first went to college, I got lost on campus! Think about it, how big can a campus be? I get lost because I have been studying at ordinary times. We seldom go out for a walk, we have no sense of direction, we don't remember the way, we don't look around, we don't remember it in our hearts. Nothing, it's not difficult, really! I'm just not used to walking. If I often walk outside, I will naturally … this has nothing to do with IQ! Is the environment! There are more opportunities in unfamiliar environment, so you can exercise.
