How does the imagination help? After all, your imagination is just in your head, right? Well, it is in your head, but is has more power than you might realize.
Your imagination speaks directly to your subconscious mind and when you imagine something strongly enough your brain cannot tell the difference between the imagining and reality.
This means that you will feel all the emotions associated with that imagining.
Let's consider a situation in which your son isn't getting his homework done.
If that happens consistently, his grades will suffer.
Let's look at his pattern.
He gets home from school, grabs a snack, and then sits down to play games on his computer.
This is not a useful pattern.
He knows his homework is there, but he puts it off because the "negative" emotions associated with doing the task keep presenting themselves.
He needs to change his pattern by using his imagination in a different way.
Instead of imagining the "doing" of the task, your son can imagine having the task done.
If he actually sees his homework done, really sees that in his mind, he will then experience the feelings that go with that, as opposed to the experiencing the feelings that are associated with actually doing the work.
He can imagine a pattern that includes his homework getting done after school and his whole evening being free so that he can do whatever he wants.
In other words, you are teaching your son to change the imagined scenario to invoke positive feelings instead of negative feelings.
This will empower him to get the work done on time.
