Excellent post my friend. Mindfulness, connecting negative thoughts with positive memories. Re-mapping the mind. This could be a good exercise, or do this when those negative thought-loops come to town. Mental health is no different than physical health. You have to work at it everyday like you would with weights or cardio. I'm researching this topic, with psilocybin and how it can re-map/re-wire the brain, flip-flopping these types of negative thought-biases and connecting them with positive stimulus.
