Murray is hilarious, and spot on. I've made stupid decisions that were downright bad for me; I still do from time to time.
The real thing we need to watch out for, however, is making bad decisions chronically. These poor decisions are so detrimental to us precisely because we make them habitually.
Because they can have significant repercussions for our future, it’s worth taking the time to try and identify them. Spend some time today evaluating your daily decisions. Can you identify an unhealthy choice that's chronic? If so, how can you correct it?
