How to use your willpower?

There are two ways of using willpower in your everyday problems.

You may concentrate upon a definite plan and bring it into effect―or not, according to the amount of force at your disposal―or you may will that the best and highest and wisest plan possible be demonstrated by the subconscious forces in the self. 

The latter commands all environments for a special purpose, instead of commanding―or attempting to command―a fragment of it.
