I keep six honest serving-men
  (They taught me all I knew);
Their names are What and Why and When
  And How and Where and Who.
--Rudyard Kipling

If you are trying to formulate strategy for your business or for your life, the six questions from Kipling's poem are still the best tools to use. 

Specifically, they are the best tools for novices. 

How do I know this? 

Because they are the questions masters of strategy continue to ask every day.
