What does "No man ever listened himself out of a job." mean?

Question

I'm a non-English speaker. I know that Calvin Coolidge said it.

I've ever read some articles that quoted this sentence. I hardly understood the meaning according either itself or the contexts. Can anyone help me?

Thanks

Answer 1

I'd suggest he meant that it's ofetn been the case where someone has TALKED themselves out of a job.

Listening CAN'T get you in any trouble, or make you look bad.

Of course....I'm taking for granted he didn't mean "listening" to other's conversations...or 'eavesdropping'.

Answer 2

Many people talk too much and have a hard time listening.  If you listen, you will have all the facts and will be less likely to speak incorrectly.  

If you listen, you are also more likely to have the respect of those you work with.

Answer 3

It basically refers to the fact that many people spend more time talking than listening.

People who are guilty of this act rarely listen to others and can lack the ability to be team players.

Those that are constantly talking miss out on key learning opportunities.
