I believe words express what's going on in your heart and your head. If you say or think good things versus if you say or think bad things, leads to where you are. Choosing what you say based on what's going on inside your heart can make all the difference in the world on your ability to impact those around you. So take time to work on your heart which will impact your head and what you think and ultimately the words you speak. After all, it's the right thing to do and it models the way for others.
