They don't. I, for example, am drawn to a certain practice but a teacher will be the one to assess whether I am ready to engage in the practice.
This works in all walks of life.
I may be drawn to formula one racing. I may even know how to drive a car. Does that mean I should immediately be given a formula one vehicle or should I go through a period of training etc... to ensure that I don't kill/injue myself and others the first time I press the accelerator?
