Proverbs 12:18

There is one who speaks rashly like the thrusts of a sword, but the tongue of the wise brings healing. 

Our words are like the thrusters to the rocket, depending on how they are used. Our words drive our lives to be successful or trouble. If we constantly repeat the circumstance and not the solution from the word of God, we will fail. We have to guard what we think and what we say.
