All persons with outward humility are not an Elmer Gantry.
what I mean is:
you have to believe in yourself--but if you are outwardly boastful, wow do you get crushed--it's tough to know just what to say about your own playing isn't it?
...it's also expected that your show your respect to the masters---yet be completely unique as well. Hard to know just how much respect to have and just how unique we are expected to be though....
that's why I play a lot of jazz--that aspect is much more clearly defined... we are also permitted just a bit of arrogance...and it's just because we play the piano...
apologies---that did sound a little harsh.
