I Think I fixed my Slice

Form the beginning of the golf season and even before this year I have been slicing miserably. I have tried to get my stance better, moved my club head around, and moved the ball from front to back just to see if I could minimize my slice. A good friend of my sent me a video (Below) and just like that at the range I am not longer slicing. I will test this out at the club tonight and this weekend and update on results.
