Hello man,
nice post, from psychological point of view. Words are just part of our communcation and most of people think that speaking is way how to express ourselves but listening is equal. And both are linked to action, which matters not just to us but as you said in your post, to other people! I posted similair post to you and It is called power of our own words, so I hope you will take your time and enjoy that...
Agreed. Listening and speaking go together with action. Action is the third element most people miss.
