netlogo - How to stop two breeds of turtles from repeating the same command? -

this first time posting, criticism appreciated! started netlogo recently, , have move way model working on. model suppose evaluate farmers join a) ecommerce or b) traditional means. both, ecommerce , traditional commerce increase farmers' wellbeing differently.

ideally, these 2 breeds of turtles join ecommerce or traditional commerce. turtles joined ecommerce evaluate if wellbeing better off once joined ecommerce. if not, traditional commerce turtle , join it. turtles went traditional commerce should decide join ecommerce if there other turtles using ecommerce in proximity. still don't have part of code since stuck on one. unfortunately, part of code:

set wellbeing wellbeing + traditional-wellbeing-value

makes turtles' wellbeing increase every tick on time. looking way prevent turtles increasing wellbeing on , on again. then, have each turtle evaluate current wellbeing , decide move if needed. below code i've come far:
