Assertiveness is the ability to express what is desired in an effective way achieving the greatest benefit without implying harm to others.
ASSERTIVITY= I respect you + YOU respect me
That is, getting others to understand what you want, your firm position at a certain point so that your rights are fulfilled without disrespecting the rights of others, to find the balance between a passive form of aggressive communication.
Passivity - Assertiveness - Aggression
The best way to be assertive when communicating is to keep in mind what, when, where, how and to whom we say.
**What** do you mean? If you are not clear about this, you can not expect others to understand it, **when** will you say it is at the moment or is it better to wait (depends on the circumstances), **where** do you locate yourself in the space of time so that the message is understood, **how** are you going to say taking full advantage of the method in which you express it, and **to whom** we will tell it without losing your effort in people who can not fulfill the objective.
In this way you can achieve what I set out at the beginning, what you want, what you need and what corresponds to you, no more or less.
