"From unhealthy desires unhealthy actions follow, from unhealthy actions unhealthy experiences follow---like an endless rotating wheel."
From: Open Your Mind, Open Your Life. A Little Book of Eastern Wisdom
Have you ever noticed that once you sink into a rut of negative thinking, negativity seems to permeate your entire life. Each moment, like the one before, makes you feel down. It's much like spiraling into an abyss so dark and black that you're not quite sure it will ever end.
There is a cure that seems so simple it couldn't possibly work, but it does. Every time you become aware of a dark thought or a feeling of helplessness, have a conversation with it. The conversation should go something like "I reject this thought and I reject this feeling. Instead I think I am wonderful and I feel great."
For those of you shaking your heads saying this is too silly to work, I say give it a try. It's not possible to hold opposing thoughts in your head at the same time. So replace the bad thoughts and feelings with positive thoughts and feelings. This will work for you just as it has for me.
IT IS ALL IN YOUR HEAD!
