Positivity. Simple as it sounds, it's a central pillar of the philosophy behind Jason Yi's Tae Kwon Do College. At each of the school's five locations, the warm, supportive atmosphere starts with the instructors. Sure, they pass along years of martial arts wisdom, but they also strive to help students—younger ones, especially—realize that having fun doesn't necessarily mean sitting in front of a TV, or arguing the legitimacy of the moon landing with an imaginary friend. Through programs for kids, teens, and even entire families](http://hellokarate.com/family-classes/), the college's instructors lead students along a path that builds self-confidence and improves self-defense techniques. Instructors build on these same skills in the college's extracurricular offerings, which include after-school programs, birthday parties, and week-long summer camps.
