Fragen über die Beispielsätze mit, und die Definition und Benutzung von "Coaching"

A: It's good English, but a bit difficult to follow. I would rearrange:

"...in their personal and professional lives due to their social skills."

'due to' just makes it clear that it's an impact of this.

A: "most important next to hard work" means "most important alongside hard work"

It is saying they are of equal importance because they are side by side.

A person above you is superior, a person below you is inferior, the person next to you is an equal.
