I just wanted to share with you my progress. I have succeeded to rotate some "more heavy" objects than psi wheels or other stuff. Here i try with a CD, i have stuck a coin in the center to put the CD on a needle.
It was the first time i succeeded on this exercise, i can do it much more easier now. Even if the "force" used here is strong enough to move a can or a pingpong ball, i can't do it. I know that i can but i have no effects. I think i have a problem with objects that are on a table, i have still strong mental walls, even after one year and a half of practice. I will continue practicing, it's the only solution i think.
