I would like to refer to a similar situation in sports, one spends months, maybe years preparing for a 1-hour sports game. Or maybe preparing for an exam at school, you will spend hours and hours preparing for a 30-minute test.
There are many other every day metaphors I can use to explain this situation, but the main Idea is the fact that preparation is a very important factor in the process of accomplish a task, it is almost like the base foundations of a house, if it is the foundations placed FIRST are strong then building the actual house be a lot simpler. If the axe is sharpened FIRST then the next process of cutting the tree will be a lot simpler due to the prior preparation.
hope this helps :)
