The only thing I have broken is my ego, my hope that I could succeed, and my fragile since of entitlement.
There was on level in Trials Fusion that was just killing me - but I was determined to get through and I quite, walked away, came back, quite. And finally, finally I made it through!
Only to find a new even harder jump, but eventually I made it!
(Still have more super hard levels to go, but it was a great feeling of accomplishment.)
