Author of Hardwiring Happiness, Rick Hanson speaks about how to use your mind to change your brain.
One of the quotes from his book that was particularly impactful to me was ...
'A key aspect of the negativity bias is the special power of fear. We routinely overestimate threats and underestimate opportunities and resources. At the same time, negative experiences sensitize the brain to the negative, making it easier to have even more negative experiences in a vicious circle.‘
It can get easier and easier to have negative thought patterns and this vicious circle is something that really has to stop.
And the challenge is to know how to make it stop. Once that's done, you can decide where you want your own inner programming to go.
