Hi Earle:
Right. There's so much out there. And students love variety, we should be mixing up the way we deliver our lessons as much as possible.
And our personality is a part of that. Variety works here too. But too much of the same, humor or levity, seriousness, monontous delivery can be a big turn off. How about passion! Excitement! Enthusisam! Creativity! Encouragement and Support! Hope! All these will contribute to meaningful and memorable course lessons.
