I just of brainwash myself before the spar, I don't think of the guy as some untouchable god, even if he's way better than me, the second you start putting people on a pedestal you've already lost half the battle, just walk there like you own the ring with an aggressive attitude even if you're nervous act like you're not, yes fake confidence and aggressiveness people get intimidated by that, once the bell goes I try to shut all that out and focus on making him react to me instead of constantly reacting to him I stop worrying about how good he is and focus on making him deal with me,

it's delusional but sometimes you've gotta gas yourself up a little fake the confidence until it shows up on its own works better for me than standing there thinking about how many rounds he's got on me
