Bertholy had some great quotes in his manual. Lots of positive thinking. A lot of things Moe Norman said came from that manual.
“Vanity is the luxury of fools.”
“The rapidity with which you learn is not indicative of your eventual worth. Your retention and application of knowledge is of far more importance.” (hope for us slow learners!!)
“Feed what you need.” ( do a drill that fixes your fault)
“Never scold yourself after a bad shot ( Tiger!), but rather punish yourself with hard work.” (precise progressive intense conditioning…PPIC as Bertholy called it)
