Last weekend gave me lots of new inspiration, as if something fell on its place.
Among many other things this is what I especially picked up:

– explaining things in a simple way
– digging in the keys will stimulate memory (don’t be to timid, exaggerate tone)
– let pulse dictate the music
– don’t think too much
– finding important notes in a piece, only playing important notes as an exercise (even as a composer I sometimes go too much into detail, instead of just following the base line)
