So far I think it was "Only care about the clarity of your message". Advice given from myself to myself.
I started an identical thread a while back! Mine was to sing everything possible before touching the keyboard - especially lyrical pieces.
I don't recall that thread you created but I believe you. Sometimes a thread like this deserves to be tossed around. Mine was 'listen to what you are playing' and that is the golden rule of piano playing. Weird, but hold that piece of advice in high regard. Every now and then I would read some of Bernhard's (I wish he were back) posts and some I find too long and too good. JL
