What is Plan D habit change planning? It is contingency planning for your habit change issue. You brainstorm possible obstacles or likely hindrances that could stop you from succeeding with your specific habit change goal.

What if the school calls and you have to go pick up your sick child at the exact time you had your workout scheduled?
