We are like pebbles, tossed into a still pond. We cannot say what happens to the ripples after that. Once they go out, they will do as they will.
The same with us.
We can't really control the effect that our words and deeds and actions have upon the world. Of course, those of us with good intentions, certainly want the currents to be helpful and not harmful to others... but then the intention belongs to us... the ripples belong to the world.
So don't edit yourself, or second guess what MIGHT happen... especially if that causes you to do nothing because of fear.
Just be the best pebble you can be... and go out and make a big splash upon the world!
Keep the light on!
