Good skills are essential, and they start with listening. The ability to interact with people in meaningful ways on a daily basis is essential to the long term relationships we want to build with them and to the impressions those people will have of us.
One thing yo avoid is having to be right all the time. Many people make this mistake and in their desire to always be right, they inhibit constructive communication and prevent relationships from developing. Your goal is to communicate better, not to win every discussion or treat every conversation as if it's a contest with a winner and a loser.
You always must communicate both your needs and goals to other people so that everyone can benefit from this knowledge. People want to know why they are being asked to do things. They want to feel they are part of the process. So don't things fester. Confront problems immediately because if they are not attended to and dealt with, they invariably get worse.
The key is not to burn bridges.
You are trying to create allies , not enemies.
