This pesky little dichotomy can cross you up making your life very unsavory if you let it. Let’s examine the difference between the two. First, “reaction”, we react to stimuli every day, one example would be if someone cuts you off in traffic. Your first reaction might be, “I’ll kill that Mother Fucker” or “That stupid ass silly son of a bitch is going to kill someone.” This is also known as a knee jerk reaction.
Now let’s take “response” (think prepared, mindful, intelligent and/or use of wisdom). Your thoughts might then be, “that bloke is in a terrible rush, I wonder if there is an emergency?” And you may pray that he makes his destination safely. No really.
Understanding the difference will certainly help you in the navigation of life’s’ struggle streets. The key is preparation of the mind and body. Without preparation you will react instead of respond every time. This is a choice, and I would recommend getting control of your thoughts to make it a wise one. (Meditation helped me gain control)
