Bottom line

TKDTutor contains numerous topics that cover practically all aspects of taekwondo, in specific, and the martial arts, in general. A great amount of information is contained in these topics. What do you really need to know? Below are most all the things you really need to know. Everything else is just superfluous mumbo jumbo (foolish or meaningless incantations; or ritualistic or ceremonial nonsense).

Best Art

A person with good athletic skills can be an effective fighter in any martial art. Some arts specialize in some aspect of the martial arts, such as kicking, throwing, grappling, etc., while other combine all or parts of other martial arts to form another martial art. While there is no one best art, there are plenty of arts that are rip-offs. Like in any other decision you make, do a lot of research into the subject.

Choose

Pick a martial art that best suits your needs. Pick a legitimate instructor that you like and who has a reputation as a good instructor and who does not rip you off or belong to an organization that will rip you off.

Learn

Learn all you can and critically analyze all you see and hear.

Train

Work hard and train as much in class as you can. Train at home as much as you can. Cross train in other sports when you can.
