I'd say the big turning point occured on the 2nd ascent of The Disappearing Floor route on Mt. Hardy, a climb inspired by Dan and Forrest's TR here on the forum.  50ft out, pulling a 5.10 mantel very much at my limit, onto a ledge which looked more like a litterbox, is the first time I REALLY had to keep it together, and it all started here.  
  
Serious fwappage.
