When you really empty your mind, you can do wonders.

I lined up 7 empty varied size plastic bottles on my car and put the trashcan on the other side where I couldn't see it. I smoked a bowl and meditated (just emptied my mind--mindfulness) a little bit and gave it a try. I visualized the bottle falling inside the trashcan right before I threw it, and upon throwing it just free'd my mind from any thoughts.

I made 6 out of 7 into the trashcan, it was amazing.
