Training is a great opportunity to receive user feedback.

Successful computer system administrators address the concerns of users.  Users have a unique perspective that can only come from real life experience using the system everyday.  They will be the first to notice problems or come up with ideas to make the system better. They care about their jobs.  They will let you know what should be done to make their job easier, more efficient, and help them meet expectations.  Users ideas and suggestions need to be fully appreciated and used to make improvements.
