“What you are speaks so loudly I can’t hear a word you’re saying” goes an old saying. And, Benjamin Franklin put it this way, “The best sermon is a good example.” More important than what we SAY it’s what we DO.
To lead others we must first be worthy of following.

Complaining reminds us of all the things we have to be miserable about.
When we stop complaining about things we find all the wonder that IS good in our lives and we become happier.
