start by not giving a fuck about results
then forget the fuck about fullring
at the table, don't think about "what the instructor did", fuck him
this is poker after all, not drivers-ed
start by understanding poker concepts, and apply them to your individual spot
notice I wrote "understand" there, not "know'
then apply game theory to influence your individual decisions, and in close ones (most, actually) focus on the long term
ta-da
