Answer: First of all, the definition of abstinence is the act or practice of refraining from indulgence in an appetite, as for certain foods, drink, alcoholic beverages, drugs, or sex. I do not know what u are learning, and the characteristics of the people being talked about. If you send a photo of the page so I can understand what background of the question. A brief overview of some strategies you could use for different people are, letting them know your past and the problems you went through. This one in particular is used for more of drug and alcohol addicts and if they are being pressured into using them again. Another way is letting them know your beliefs. For example, abstinence in sex. If you are Christian and believe that you should save sex until marriage, then let them know. Another one is letting them know your goal. For example dieting and refraining from certain foods. If you have a certain body goal and you are out eating with family, tell them your goal and stick with it.
