ionno, im a lot newer than most of you guys...
what I usually do is pace around the platform during my rest (around 2-3 minutes) giving myself a pep talk...
when i am about 20 sec left in rest I go to the bar, get in my stance and stomp hard 3 or 4 times, i find that really clears my head.
Finally, when I am ready to lift, i say to myself as i do it:
By the time I get to realizing I passed Step 5 the bar is either on my shoulder/over my head or its a fail.
But what do I know, only been cleaning about 5 months now :P
