Philosophy of the DOER

Can it be that there can be no instructor for the doer to do what need to be done? Is it possible that the doer himself is the instructor? And is it possible for something completed to be completed by the doer without any instruction to do it? Suppose that an instructor is required by the doer; If an instructor is also the doer, it is impossible for the doer to to without instruction, and if the doer is not willing, the instructor contradict himself for being the doer at the same time.
