From a technical perspective of teaching an attack mindset , I always reference the relationship
instead of watching yourself or your opponent , I Advocate watching the interaction(gap,relationship) between you .
you are either meeting, or yeliding, joining or leading you are never blocking
by establishing this relationship you can find the joint mass centre , the cumulitive centre of the confrontation.
whoever has the momentum across the JMC has the upper hand and the power momentum and positonal advantage.
by understanding and seeing this relationship you find that defence comes from being first to this point , this can be done moving in any direction even backwards as its arriving at the point between you first , it is in essence a closing of the relationship. if you are both moving the same then the relationship does not alter , by watching the relationship you are simplifying the dynamic.
hopefully we instill a desperation to be the one to arrive and control this point.
also earlier I mentioned neutral stances, while I do this for the more advanced there is another reason above being the most likely stance you are to be suprise attacked from .
It necessitates moving into a stance attack , this accomplishes two crucial things.
1) it makes you move in the direction your going attacking(

I know sounds obvious but so many get this wrong)
2) it makes you leave the position being attacked .
the very opening of kata shows this IMHO , Max Ainley was the one to really emphasise the start of kata to me , and I beleive this is one of the reasons , to explode out of neutral and find your power into your techniques . stance and technique being were you end up , with momentum and with aggression.
while the intent must lead the technique , by making the logic of the technique require the mindset, we point the mind in the right direction and lead hopefully towards right combative thinking.
