[support] How to become a master module builder

Hi, I'm rather new to Drupal but not LAMP. I'm trying to learn how to create a module so I followed https://drupal.org/developing/modules/7 ... I learnd a lot, however I do not fully understand what I need to do to add a check box to the article pages, save it's settings....etc. I think I might be able to muddle through making a block since that is what the tutorial was about. Any suggestions on how to go from confused to master module maker? Thank you for your feedback!! Keith
