Thus, the first law I will obey, which precedeth all others is—I will form good habits and become their slave. Og Mandino
I met this concept in the 70’s. Water will follow a channel. Thoughts also will follow a channel. I learned to channel thoughts by mentally singing words and notes to a song. When an unwanted thought crosses my mind, I drive it away by singing this song.
That skill has been very helpful during the 7 day mental challenge. Do I recognize and banish unwanted thoughts in the first 7 seconds? No, but not many survive longer than a minute.
