Try to control what your lips pronounce. At first, you can give yourself installation speak the truth at least twice a day to ease the process of getting used to. Gradually, day by day, the number of truth in his conversation as long as it does not reach its maximum. Let all that you utter during the day, be true.
Make a decision about what going to do in contentious situations. For example, you work for a company that sells dairy products. Did you find customers among the regular customers are ready to buy a huge consignment of goods at a discount. On the same day the boss found a buyer willing to buy the whole volume of production at the price without discount. What do you do in order not to lose a regular customer, which was originally agreed? May wish to describe the situation to him without details, for example, mentions the intervention independent of your circumstances or a higher power. Instead, you can simply lie not to say anything. Or you can choose to tell him everything as is. Sincerity impresses many.
If you are entrusted with secrets, but a close friend or an old acquaintance wish vyznat it from you, do not give in to provocation.
