How do you step from the top of a 100 foot pole

A famous story from Zen literature presents the provocative question, “How do you step from the top of a 100 foot pole?

The poem that goes along with this question says:

You who sit on the top of a 100 foot pole
Although you have entered the Way, it is not yet genuine
Take a step from the top of the pole
And the entire world becomes your body

So, how can u make one step further if u are already on top? This seems to be impossible, because you cant either go further nor can u go down from the point where you are standing. If we look at it more precisely there is no such thing like “top” in life. People might think they achieved everything in life they aspired to ,they feel comfortable where they are, they feel they now understand life and see everything clearer but life is all about development,improvement and progress. 

The world won't at no point stop spinning, nor can we stop to progress,there cant be stagnation at no stage in life. We live and we learn every day in our lifetime, either from a situation we are in or from people we are surrounded by, from the things we see and hear. That progress might happen unconsciously sometimes, but we are in it as soon as we open our eyes every morning. People who would consider themselves being on top and thinking they achieved everything in life have stopped to live because their mind, heart and soul is closed from their wrong perception. So stepping further from the top of a 100 foot pole, is only a small step out of countless steps in life.
