Wonderfully penned down. You left no stone unturned and your use of image is illustrative enough.
Nothing is as hard as teaching a demotivated student, nothing could be compared. I remember when i was doing my National Youth Service Corps (NYSC) at Bayelsa state in Nigeria, it wasn't an easy one. The indigenes of the community i was posted to teach, are allergic to knowledge, dull and demotivated.
I was opportuned to take my students in Computer classes, sometimes i had to sit on the floor, pull of my clothes and jump through the window just to illustrate classifications of a computer system. Most times i use my resources to encourage students who will ask the most questions and the ones that attempts to answer.
It wasn't easy at all, but that is the true act of teaching.
