So now you know 6-Blocks, right?

The sequence as it stands is (let’s call this Version 1) :-
6-Blks-1
6-Blks-2
6-Blks-3
6-Blks-4
6-Blks-5
6-Blks-6

Now try practicing it in an reordered sequence (Version 2) :-
6-Blks-1
6-Blks-6
6-Blks-5
6-Blks-3
6-Blks-2
6-Blks-4

If you are really familiar with Version 1 you should be able to pick up Version 2 within half an hour.

Go through it a few more times and in the next hour you should be able to do it easily.

By night you should be able to do Version 1 followed by Version 2 without hesitating.

By end of the week you should be able to move faster without missing a beat.

The whole point here is not to actually learn a new sequence but to teach your mind to break out of a fixed sequence.

For example, Version 2 could very well look like the sequence below (we will call this Version 3) :-
6-Blks-3
6-Blks-6
6-Blks-1
6-Blks-2
6-Blks-4
6-Blks-5

After a while you will find that during application of technique you can move to any of the other 5 blocks from whichever block you are in. At this point, you can say that you have gained competency in the 6-Blocks.

Later, when you add on the other hand to do a two-handed version of 6-Blocks this will become clearer.
