Changing Of Lives

Have I ever expressed something to someone that changed their life? Was it my intent or was it said without thought of the effect? It could be that I have had a hand in changing many lives and that may not be good. It may be that I have had very little effect on anyone's life and that may not be good. I think maybe I should give more thought to what I say before I say it. In doing that it may only be me who is effected and that in itself may have a good effect on someone else.
