The importance of persistence in life cannot be overemphasised. Many goals in life won't just deliver to you at your first attempt. Many times we must try again and again before we finally master our game. So, if you don't learn how to persist, you may soon be caught in an unfortunate web of "giving up".
Absolutely @zapplwoman, it is important to learn how to persist.
