Imagine that thoughts are like drops of water

One thought, just like a drop of water, means not much.
But here you repeat the thought over and over again, and first a wet spot forms on the carpet, then a small puddle, followed by a body of water...
And then a lake, a river, the sea, and finally the ocean.
So what kind of ocean are you creating?
Polluted and poisoned, so dangerous to dip your toe in?
Or is your ocean crystal clear and beckoning to enjoy the refreshing waters?
