Our Thoughts Become Things

Since first hearing these words from a woman whose focus changed the world, I have scrutinized the last line "WHAT WE THINK, WE BECOME."I've wondered is this true? If so, how do I stop from thinking negative thoughts? Isn't it true some negative thoughts can help prepare me for possible outcomes in a situation?According to scientist using fMRI technology, we very well may become what we think. The scans show neuronal pathways lighting up separate areas of the brain depending on if we are thinking about positive or negative thoughts. These thoughts then reinforce the neuronal pathways in that area of the brain.As for stopping negative thoughts, it turns out to be similar to breaking any other habit. It is a matter of stopping the negative thoughts as soon as they are noticed and purposely replacing with a positive thought; while each day setting a goal to get 1% better.Lastly, I do think that it is important to consider both positive and negative outcomes to be better prepared. For me the key has been to watch for the moment when my negative thoughts are no longer useful.
