How do you make appointments smoothly?

Only make agreements that you plan to keep. Carefully consider the importance and necessity of the appointment. Think carefully about the investment of time and energy you will need do to keep the appointment. Write down your appointments. First of all, not to forget them, but also to limit them, to oversee them and to respect their content. Communicate if you cannot keep an appointment. Leave it that way know as soon as possible if you cannot keep an appointment, make a new one. Do not do it. Say 'no'. Don't make the appointment. Think about it carefully and decide what is the advantage of entering into the agreement or not.
