You cannot disgrace a disgraceful man; you cannot make a shameless man feel ashamed; you cannot make a cockroach a cockroach, because it is already a cockroach!
If you want to say something truly new, you must first know everything that has been said in the human history; not half, not ninety percent, but all that has been said! Only then you can say something new, if you can!
A good teacher always refuses to have disciples! Let everyone goes his own way, in his own path instead of following others! If the direction is correct, there will be a meeting in the same place!
