We should always ask ourselves questions on why we are doing certain things/actions in life.
We should determine their true purpose and decide whether it is important or not to accomplish them.
So now we ought to ask ourselves this question: why is developing communication skills important for us?
It is as simple as it looks; we live in a world that relies on communication. From telling our parents that we are hungry during childhood to performing a live speech in front of millions of people, we need those skills to effectively deliver the message. In every situation, we (as creators of the message) are supposed to find a way to get the message through to the audience. This requires communication skills.
Every person we are talking to is the audience. Since each person is different, it requires us to find a different way to interact with him/her. If I were to organize a trip with my friend, there should always be a mean of communication between us. It does not need to be formal, but it needs to be clear because we (my friend and I) do not want to end up separated in different countries. If I were to talk with my superior (Manager, boss, CEO, Prof, etc ...), using any communication channel (e-mail, phone, face to face interaction), it is important to be formal. Thus, to determine how to deliver a message, we need communication skills.
It becomes harder when the audience is unknown to us (when sending our resumes to a recruiter). It is also difficult to adapt in different situations and contexts. Finally, if our audience includes more than one person, how can we arrange to get the message through without having to separate each person and persuade each one of them in a different manner?
Good communication skills will turn every obstacle that society throws at us into a mere insignificant and unnoticeable setback. It makes it easier for us to achieve our goals through efficient and strong communication. This is why we need good communication skills.
