My one piece of advice is… throw angry!
Remember that yo-yo is your enemy and you gotta fling it as hard and as fiercely as you can! Don’t let that little piece of junk get the better of you! Show it who is boss! Beat it up! Punch it and put it in a headlock if necessary! Shout and scream and yell at it to demonstrate your superiority over that dumb yo-yo!
nobody said it had to be good advice
