For me, I first need to get to the point where I know exactly what makes my jump work or not work, from a technical standpoint. This can sometimes take quite awhile, since it involves trial and error (and a very observant coach), but it gives me very specific technical things to focus on as I execute the jump in practice and in competition. If I am feeling hesitant, I pretty much have to scream my technique cue words at myself inside my head to drown out the self-doubt and distraction. Having said that, the 2Sal is my most mental jump, too. The timing and the pressure on the blade have to be just so. . .
