Discipline Equals Freedom Field Manual by Jocko Willink ( PDFDrive.com )

WHERE TO TRAIN
When picking a good jiu-jitsu academy, first things
first: Find some schools that are in your immediate
area. Proximity is important. The more convenient it
is to get to training, the more often you will be
able train. So find some schools that are close to
your home or work or some other place where it isn’t
an out-of-your-way gut check to show up and train.
Once you have identified some academies close by, go
and pay a visit. The atmospheres in gyms can vary
greatly. Some are very traditional, demand matching
uniforms, bowing to instructors and to the mat, and
are run in a very rigid manner. Other schools do not
operate with that tradition. There is no bowing. A
wide variety of uniforms can be seen on the mat.
Instructors are called by their first names instead
of “Master,” or “Sensei,” or “Professor.” I have
trained in both these types of schools, I am fine
with both, and both types have produced world
champions. You may end up preferring one style or
another, but when you show up, don’t have any
preconceived ideas of what the school will be like.
Also, don’t just show up and watch. Bring your gear
and participate. Evaluate the class. How was it
taught? What was the attitude of the instructor and
the other students? Talk to the students. What are
their goals? Are their goals similar to yours? Was
there much ego on the mat? Did anyone try to rip your
head off?
