A character stepping out of their 'ordinary world'

The following excerpt, based on the famous Hero's Journey approach to story,is from Heroes: A Guide to Realising Your Dreams:

The ordinary world is the environment in which most people live. It is the place where people often feel most comfortable but is also a place where they feel their dreams can be drained out of them. While the ordinary world may be a great place to rest, it is a stifling place to live your dreams.

Write a story beginning with a character coming to feel stifled in their 'ordinary world' then deciding to take the first step toward something they consider more fulfilling.
