1) Have a positive experience (e.g., enjoy a cup coffee or tea with a friend, watch a sunset, think about events, people, and things for which you are grateful).
2) Absorb the positive experience (hold on to the experience in your mind and visualize it).
3) Connect the positive and negative thoughts and experiences in such a fashion that positive experiences replace negative experiences (e.g., if a negative thought enters the mind, let go of it and focus on positive thoughts instead).
The fact is, the brain is changed by experiences of the body, the mind, and the spirit. All mental activity (e.g., sights and sounds, thoughts and feelings, conscious and unconscious processes) is based on underlying neural activity.
Remember, whatever you repeatedly think, feel, do, and sense, changes the neural structure of your brain. The experience of happiness creates positive changes in the brain’s neural network.
