On their own, thoughts are not a problem. Believing them, taking them seriously, identifying with them—now that’s a problem. The challenge: Don’t believe everything you think. Timesaver: If it’s negative, dismiss it.
To slow your thoughts, watch your thoughts. Just notice them. Don’t judge, analyze or otherwise engage with them. You have opened the door to an unsupervised classroom full of nine-year-old boys. Watch them.
