If you do not show & convince the students that you have passion for the subject.  

They will never develop one either. 

The module reinforced the idea of  'Lead by example'. You want your students on time, you be early. You want your students to look the part, you look the part. You want no vulgar or offensive in the class room, You don't use it either, regardless of the situation. These are the principals I intend to enforce on my students & mostly upon myself.
