If you work with clients on a regular basis, it's important to always be on your "A" game. Here are a few universal skills that every good employee should master:
Communication
If you can’t communicate well verbally and in writing, then it’s time to learn:
Respect
Treat others as you would like to be treated.
Patience
Don’t rush people, make sure they feel heard.
Knowledge
Never be the person who doesn’t have the answer to a question.
Adaptability
The ability to read people.
Creativity
Think outside of the box to solve a problem.
