You can go to school to learn history, geography, literature, science, and many other subjects. But you cannot learn street smarts in a classroom, in fact, you can't truly learn street smarts until you've lived and learned for yourself.
Nonetheless, there are tips you can take out into the world with you to help you navigate it smarter and safer, and absorbing the street smarts of other people can literally be a life saver.
