So there is this beginner I know, hes my friend. He considers me to be his mentor but he is very stubborn. He doesnt listen to me and does or says stuipid things sometimes. he performs angle sensitive tricks at the wrong time, argues with me etc. What makes me mad even more is that he knows im right but still argues. Another thing is that he doesnt perform tricks, and never practices. He has been trying to do the thumb fan for thelast 2 months, and he says he practices. I feel he is too lazy to even learn a double lifta nd he complains when something goes wrong. He thinks that evrything happens without practice. Everytime he sees a trick he says " i wanna learn that" and then quites on it when he finds out the sleights. He is too lazy to practice them. What can i do to help him and understand what this art is about. Any tips guys? Thanks if you read through the whole thing. Please help.
