text: the trick- YOU MUST DO THIS - find your comfort level with whatever it is youre doin- the pace, the intensity, the resistance, find it- keep it, then- when youre all out of energy- keep going you're gonna be fine its just burn it only lasts for a minute till you feel your second wind then you'll be unstoppable - another secret, remind yourself when you feel you cant (why can't you? not because your body can't take it (it can) remind yourself that there's no real physical injury happening and the pain and resistance will no longer be associated with what you're doin but a separate nuisance that you CAN AND WILL tolerate (only for a short time till your stamina is tougher than zeus!) don't be stupid though - know and don't push real limitations -when you injure yourself it's gonna take forever to heal -
