Great video from Tyler on this:

I laughed my balls off in the 7th minute when he talks about things that distract you like getting comfortable & maneuvering yourself during your session, & in particular gettin an itch "just accept that this fucking annoying little itch is there, but your not gunna scratch it" ... This happened to me earlier on this evening & i said this to myself literally word for word.

The spot he shot this video at is also awesome.
