Bindo, I am also a projector, though no a mental one.
I will write down what I believe to be useful if I were in your position.
I believe it is good practice as a projector to let others know what your ideas are and let others know what you are doing.
Meaning two things:
1- since you are a mental projector with no inner authority, you need to engage in talking things with others so that in this process you can recognise "the pattern" of what would be good for you to do. So telling your teachers that you' ve got that idea and discussing the idea with them is one way of being your "Self".
2- as a projector it seems good and effective practice to let others know your ideas, for instance that you would like to join Ra on-line and that you would want somebody to help you with the payment (and you go on and explain how you would pay back etc etc). This is one way you will eventually get invited to things or not. You could eventually being invited into a negociation of the kind you want for the course payment.
It seems good practice to let yourself be known and after that to let go of your "original" purpose and wait to see what happens.
