Every customer service teacher I know has a book or two to offer, and there are many related resources available for minimal cost - sometimes free.

So if you want to improve in your field, to lead the way and excel at what you do.....get reading.
There are countless videos on websites to watch and learn from too, if you make it a daily habit of watching just a couple a week think how much knowledge you can pick up in no time.
Remember, what you do at your job just pays the bills......its what you do with your spare time that creates your future.
