6 Harmonies & Forms

So I have been staying very focused on the 6 harmonies in my forms ... its been frustrating to say the least.   It does not seem to matter which form I do I am like a light fixture thats shorting out.   I will go thru parts that flow really nice and I am feeling it ... grounded ... feeling the power moving thru the movement and then pfft, the light goes out and nothing!  Mostly it happens when I am not in a horse stance or bow stance ... there is something not 100% correct in the cat stance and when I do things like attacks to opponents behind me or I am retreating.  Maybe its just my visualization/interpretation of what is happening that messes me up but I crash and burn badly in those types of moves.  Sifu Brinker yet again explained the harmonies in the cat stance ... so the plan is start with the move before a cat stance and the move after in a number of different forms and hopefully I will be able to establish the connection/flow throughout.  Wish me luck!
