thats old shool and is very simple to overcome , you have to do it in thought a couple of times , then you should overcome it
this is what you should do
draw a 6 in the air at least 5 times , while you do this turn your right foot clockwise in THOUGHT
after doing that try it again
prolly wont work,
now turn your right foot clockwise five times and draw that six with your right hand in THOUGHT
after doing this couple of times you should be able to do it without a problem because you will overcome the block that does this in thought first and then it should be easy to actually perform
