I was taught as a child: "What you put your attention upon you become" I have always found this to be true in real life

So, putting your attention on the right things brings a good life.

I found at a Saint Germain Foundation site the more involved version of the statement in the Title of this article. Here is the fulness of this statement likely from Mr. Ballard in the 1930s when he was still alive:

"What you think and feel, you bring into form:

Where your thought is, there you are,

For you are your consciousness:

And what you meditate upon you become."
