D.
this is because of my goal was to walk 30 feet for example, my experiences with walking 10 feet would not motivate me to want to walk 30 feet.
a reward would motivate me to walk 30 feet because i like rewards and would feel motivated to earn it.
be believing that if i walk 30 feet i’ll burn 2 calories will motivate me to walk 30 feet because i will believe i’ll be 2 calories lighter.
me valuing my exercise would motivate me to walk 30 feet because if i didn’t care i just wouldn’t.
