We talk, all the time. It isn't a job thing. You find yourself communicating all day long, in fact, most of those conversations are made on autopilot; you just know what to say, your brain is that amazing!
The problem with autopilot is, if you aren't careful, you soon lose track of what you are saying and start to make no sense. You soon start to produce useless words just for the sake of talking. Do not be that person that spill just for the sake of it.
Here is the deal; if your words are not adding value, then they aren't valuable. What I mean by valuable is edifying, impacting, influencing, improving those listening to you.
There is a reason the Bible says "Let your words be few" Ecclesiastes 5:2 and Ephesians 4:29 "Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up (edifying) according to their needs, that it may benefit those who listen."
It all adds up right? From the ones you say to yourself to those, you say to others. What you say to people might make an impression, but what you consistently say to yourself will time begin to produce fruits after its kind; good or bad.
Do not start a conversation without a purpose in mind. In fact, when you are dragged into one; quickly book a purpose in your heart; if you cannot find any reasonable one, excuse yourself as soon as you can. With purposeful few words; You soon realize how impactful your words will become, and pretty sooner, everyone around you will too.
