All around you are reminders on how you grow. The lobster is a good example of this. Its growth depends on the shedding of a series of hard, protective shells. The shell that protected and served it well at one stage eventually becomes too small for its expanding body. If the shell cannot be dropped as the lobster expands, it will smother and kill the fish. But letting go of the shell is also a risk. When the hard, protective cover is gone, for a time the lobster is left soft, pliable and vulnerable to attack. It is only in this soft and pliable state that it can create a new and expanded shell that allows for continued growth.
