I missed a day moving ahead but what I did was rewatch three previous lessons writing down all the code via paper/pen so I could see the changes in a more linear fashion to totally understand…
I think I understand colliders, and limiting the paddle now and position.x of the mouse.
This is a Friday so I cleaned house throughly and cooked a huge meatloaf to last my husband all weekend so I can study and not feel guilty. 
I’m ready to move ahead now.
Fixing to start Distance as a Vector!!
