The method is fully explained in the Natural Brilliance book, there is even a script for the self talk to follow a Direct learning session. You are also guided through the process in the Genius Code course.
As for learning different subjects give them each their own time. Doing an all at once thing tells your mind 2 things, That you don't know what your priorities are and that it isn't really that important.
When you do a direct learning focus on one subject and affirm your intention to adopt the behaviour or necessary actions that will be applicable to what you desire to learn.
For example if you want to be a better manager focus on management books and then see yourself behaving as a better manager. This might include better communication skill, better orgainsation and delgation skill, better motivation skills. Since all these things would usually be covered in the subject of management you can expect to perform better in those area. Keep a journal because the changes will seem so habitual like you've always been doing it that you may not even notice until someone else comments on the change.
