The Secret is Building New Neural Pathways through Interview Simulation.
All your memories (of events, words, images, emotions, etc.) thus correspond to the particular activity of certain networks of neurons in your brain that have strengthened connections with one another.
Every time you learn something, neural circuits are altered in your brain. These circuits are composed of a number of neurons (nerve cells) that communicate with one another through special junctions called synapses.
When you learn something, it is actually these synapses whose efficiency increases, thus facilitating the passage of nerve impulses along a particular circuit. For example, when you are exposed to a new word, you have to make new connections among certain neurons in your brain to deal with it: some neurons in your visual cortex to recognize the spelling, others in your auditory cortex to hear the pronunciation, and still others in the associative regions of the cortex to relate the word to your existing knowledge.
To learn this new word, you repeat it to yourself several times, and this selects and strengthens the connections among these various circuits in your cortex. And it is this new, durable association among certain neurons that will form your memory of this word. The strength of this association may of course depend on several factors.
To remember the word days or years later, you will have to successfully reactivate these same neural circuits. Obviously, this will be easier if, when you first learned the word, you built these circuits to last, by repeating the word and thus sending the corresponding nerve impulses down them many times. In contrast, if you repeated the word only a few times, then the connections among the new neurons would be weaker, and the new circuit would be harder to reactivate.
Practicing new, more effective behaviours actually builds new neural pathways in your brain. These pathways make it easier to repeat these emotionally intelligent behaviours in the future. Without the repetition that comes with regular practice by Interview Simulation the pathways will not form and you will not change.
