A reaction is instant. It’s driven by the beliefs and biases of the unconscious mind. When you ‘react’ to something, that’s the unconscious mind jumping in, it doesn’t take into account long-term effects...A ‘response’, however, is more thought-out. It’s takes into account information from our conscious and unconscious mind, balancing it all and weighing everything up.
Planning means to think things through before they happen - it means thinking about how you are going to respond to things. If you are a little overweight and decide to start a new fitness regime of running first thing in the morning, you have a much higher chance of success if you lay out your running gear on your bedroom floor the night before. It means that you are PLANNING to remove the ‘hassle’ factor in the morning.
