Do the opposite of what Brock does.
Expect to get hit, don't let it bother you. Training your defense is as important as your offense.
I know you think otherwise, but expect to gas. You could get an adrenaline dump your first time sparring.
Circle, stay calm, and work your techniques. Try to learn how your opponent reacts to your movements. Like poker, look for tells and use them. e.g. if he always slips/blocks the same way to your jab, fake the jab and punch where he will be. You should pick up some patterns in the first minute or so.
