When a human being gets superpowers he simply misuses (with VK this is impossible), or forgets and does not use his or her powers since their thoughts are overwhelming them to an extent where they don't use their powers and act on a particular situation. WELL HERE IS A TREAT!
With VK, when I say requests out loud or mentally, I am always concentrating to repeat the exact same phrase 9×. I know VK follows each and every thought of ours however my mind does not relax until I have repeated the request 9× perfectly. Well here is a solution.
Write down a bunch of requests for VK, and record it in a quite place. DO NOT THROW THE PAPER, THERE IS A BONUS ADVICE NEAR THE END! After open a free audio editing software, I use Audacity! Import your recording. Then split the track, so that you have splitted each of your requests. Highlight your requests individually, and go to the effect icon, press repeat, and it will ask how many repetitions you want, simply put 9! After overlay your favourite music as export as WAV (if you have sped up and pitched or changed the tempo of your request recording to speed up the duration of your requests) or you could export as MP3!
BONUS: Now you have your request audio, place your VK on the request paper and then play your audio track. This works AMAZINGLY FAST!
