“If you spend most of your time focusing on negative things and thinking unhappy thoughts, your brain will release more of the neurotransmitters associated with sadness and less of the ones associated with happiness. Over time, your brain adjusts and not only doesn’t MAKE as many of the ‘happy hormones’ but also loses its ability to RECEIVE the ‘happy hormones’ it does make.
This is the scientific basis for ‘We become what we think about most of the time.’ Why? Because thinking stimulates neurotransmitters which then create new receptors!”
