R-tard, here...have never taken a lesson...But please take a frickin lesson.
Some random folk gave me 3 concepts that immediately and substantially helped. They are really about position or postural form.
First, keep all your body parts inside the cereal box...the board is the bottom of the box.
Second, get your pelvis tilted forward...kind of like humping...by squeezing your butt cheeks, tighten your abs and sink abit in your knees. This basically gets your body parts stacked inside the box.
Third, use you leading knee to steer....torsional steering. Bend your knee and point it to the center of the toeside turn and for heelside swing your knee forward toward the nose...thereby pressuring the front heelside edge.
