My personal experience in personal & professional life is that the ones that talk the most are usually NOT the ones getting the most work done.
I mean unless of course speaking is your job. I.e. a "retired" politician gets paid 6 figures to "speak".

Yes me too, the talkers are the ones who know it all but do nothing. I was like that for a time and had to face that truth as well. Now, things are different. I just get on with things and if someone asks I give them a little but let them find it for themselves.
