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

someone grabs you, you are in a grappling scenario,
and one of the most critical parts of Brazilian jiujitsu
is escaping from someone’s grip so you can run.
Oftentimes, an attacker will take you to the ground
in order to prevent you from escaping their grip.
When this happens, the ability to ground fight is
used not to stay on the ground but to get up and get
away from the attacker. The first goal of a beginner
in jiu-jitsu is not to get the fight to the ground,
but to get up off the ground and get away. This is an
important distinction from people who believe the
goal of self-defense in jiu-jitsu is to get the
attacker to the ground. This is not true. The goal is
to get away. But, as has been seen over and over
again, fights often end up on the ground, and
therefore a person must be prepared for it. Not
training in jiu-jitsu because you don’t want to go to
the ground is like not learning to swim because you
don’t want to go in the water. It doesn’t make sense.
The safest way to deal with water is to be
comfortable in it—just as being comfortable on the
ground is the best way to deal with that scenario,
should it unfold in real life.

Another reason I recommend starting martial arts by
learning Brazilian jiu-jitsu is because it is the
most complex of the martial arts. Although there is a
finite number of basic moves and positions, there is
an infinite number of moves beyond the basics, and
more are developed every day in this constantly
evolving art. Due to this unending depth in jiujitsu,
it is also the most cerebral of the martial
arts. It provides incredible mental stimulus and a
never-ending challenge to learn, develop, and
improve. Jiu-jitsu never gets old.
