Imagine you spend 30 minutes a day commuting to work and listen to classical music during this time. Now imagine you listen to heavy metal on full blast for 30 minutes instead.
Now imagine it’s not music, but thoughts. 30 minutes of positive thoughts like, “I’m glad they’re rebuilding the road so that it can stand up to a big earthquake,” or 30 minutes of negative thoughts like, “I can’t believe they chose that corrupt contractor to rebuild the roads, and with my tax dollars. Sheesh.”
Now imagine it’s not just 30 minutes. It’s all day long. And you get to choose what to listen to.
