There are three general groups that create confidence. They are:
1. Physical Conditioning
2. Physical Skills Development
3. Strategic & Tactical Conditioning
The simple message here is that your body must be able to support the
activity. Your body/mind system must be able to perform movements to
skillfully address the problems and your scenario training must be
able to strategically and tactically solve the problem. If you leave
out parts of this trinity, you weaken the synergy!
In the typical street scenario, always bet on basics. Scientifically
speaking, most people attack in similar ways, so it is common to find
that you're relying on the same tactics over & over. That's a good
thing. But a technique never won a fight, it was always the person
who did the work. So when you really analyze the micro-moment of
combat and contact, where the result was favorable, it was usually a
combination spontaneity, commitment and directness that won the
moment, irrespective of the style, system or tactics.

1. avoid/de-escalate. 2. Stun & Run 3. Stun & Control 4. Stun

Strike when you can, grapple when you have to. This philosophy helps
create clarity in the moment. Remember, don't use your favorite move
in a fight, and use the move that's worst for your opponent! That
takes versatility. There are times for the ground and times to stay
on your feet. Most of the time, for the street, you want to be up and
ready to move. But for real-life confidence you need to cross train.
Remember, street confrontations generally start in close quarter
range. If the confrontation is not taken care of verbally or
physically at that range, or if the attack were so sudden, it would
probably go to the ground. Learning grappling skills is extremely
important for total confidence. And if you are forced to the ground
you will not panic. You have the tools.
