i agree with them , better stick to the basics. just to get an insight, then you would know anong tawag sa ganung particular behavior and would have a fairly good idea of why people behave that way. cause and effect kumbaga.

its very interesting but very time consuming. ang daming branch at sub branch. like clinical, related dun sa mga may sayad; industrial, para sa HRD (personnel) ng companies; at school setting, like guidance counselling. under these , me

good luck!
