The post course homework is to apply the principles that you learn, in real life situations.
The work you do on the course is very engaging and interesting, and you will be inspired to put it into practice. The real test is whether you actually do what you say you will do;
Put the course material into practice on a consistent basis. (and NOT to drift back to your original habit patterns that you had before the training).
The purpose of training is to help you formulate a plan for successful action, but a plan won’t work unless you do!
