People talk about method actors, meaning someone that's prepared very, very well, or whatever they mean when they talk about it. But the right method is whatever works for you. And what works for me on any given day is going to be different.
All our knowledge merely helps us to die a more painful death than the animals that know nothing. A day will come when science will turn upon its error and no longer hesitate to shorten our woes. A day will come when it will dare and act with certainty; when life, grown wiser, will depart silently at its hour, knowing that it has reached its term.
