good points :)

Surely, Feyman can say that and genius like him can all say that... and many of our genius friends here can also say that... However, there are also many normal people, or below normal people like me :) ---- I think for these people, we should be better off first to learn what the textbook says, what the classic knowledge is, before we set out for "true discoveries". :)
Not everyone is a Feyman and not everyone can be one.
