Trying to fix your speech by overlooking the real problem (your heart) and using external techniques is like nailing fresh apples to a dead tree, sure it may help the tree look good for a short time but in the long run that fruit will die and the tree will have decayed further. You have not fixed the real problem. In communication the root problem is your heart. The fruit of that problem is your speech. So don’t assume that you can manipulate the fruit to change the root.
