Also, when people crave knowledge themselves.
Because people about who you told are the ones that need to be persuaded, sorta - it's tough work.
But once a person has a grasp and determination to learn - to teach such people is a bliss, I imagine.
But this is not a course lesson given to students, it is identical to real work and if you make the wrong decision it will result in many financial and mental aspects. Personally, I just give general information and let their imagination work to search deeper and the more they enter, the more confident they will be to enter and invest and be ready for everything that is beyond their expectations. if they ask abaout that.
