When a child is learning to write it is extremely easy for it to hold the pen wrongly and to form its letters incorrectly but it is painfully difficult to hold the pen and to write properly, and this because of the child's ignorance of the art of writing which can only be dispelled by persistent effort and practice until at last it becomes natural and easy to hold the pen properly and to write correctly and difficult as well as altogether unnecessary to do the wrong thing. It is the same in the vital things of mind and life.
