I really like this video, cleverly illustrated with an important message.

 

This is something we all can incorporate in our day and should encourage others too as well, from as early an age as possible. Build it into school curriculums, in one form or another, from pre-K through college. 
This is one thing we should all be required to do, just like reading & writing. 
This has tremendous benefits, primarily for ourselves but also quite visibly for those we frequently interact with.  

I'll let the video do the rest of the coaching!
