So what I'm looking for is not really long workshops about how to do a trick, but rather a short sentence or some words that just made you understand how to do it. After hearing this your brain would just go "ahaa!" and you were better than before.
This is one from the top of my head, will add more later as I remember them.

After applying this they would just stop wobbling.
Edit: Forgot to mention that of course it doesn't have to be a quote from someone, this could also be discoveries you have done by yourself!
