Those who are tall must use their natural traits to intimidate their opponents. They must strike swiftly and cleanly, with as few unnecessary movements as possible.
Those who aren't tall must compensate by breaking the confidence and calmness of their opponents and instead bait their opponents into attacking.
This is a basic and unspoken rule in Kumdo.
I've got to focus on my speed if I want to get good. Speed training, drills, and such will utilize my advantages to the max.
