You always have a choice. When you catch yourself repeating negative thoughts, STOP AND PRESS PLAY! In other words, imagine your thoughts like a videotape (or dvd) - stuck on the same spot. Stop the track and press play.. or fast forward, if you like. In other words, choose not to focus on that.

Bring in JOY! Focus on love, flowers, childrens laughter... anything which makes you feel good and uplifted. Focus on God's love.

In books, don't bother reading the stuff which doesn't work for you. Only take in what has resonance in your heart and soul. Don't pollute your psyche!
