No one will argue the fact that having full mental faculties is one hallmark of a successful person. Working on heightening and improving mental faculties greatly improves the chances of success in life, career, or any other endeavor one may pursue. When working on improving the mental faculties, the first obstacle is in defining what, exactly, these mental faculties are and how they work.
As with any complex structure (the mind being about as complex as it gets), it is best tackled by breaking it down into smaller components. Human mental faculty can be categorized into six major components: imagination, intuition, perception, memory, will, and reason. Defining and exploring these six components will lead to understanding how they improve our chances of achieving success.
