Once they find a disc they are doing o.k. with and youve taught them one or two things let them just play for awhile without any teaching , if theyre having fun encourage them without any learning involved just tell them thats really good or man thats great shot(even if its not that great).
Think of a noob just like a little kid , let them think they are learning on their own but if they ask for help be ready , but dont over do it. Sometimes it gets boring for us teaching someone or playing with a noob , but if their having fun just try to fake it if your not.
