Hi Jason,
Your schedule sounds like mine. I start teaching at 4 and go until 7. That group is tired and hungry. I start another group and go from 7 until 10. That group is tired and full. Either way they want to do most anything but listen and focus. This is the big challenge I find in my teaching. I find I must be a cheerleader, coach, instructor and motivator to get through each evening and to keep them coming back. I work very hard at making the instructional process exciting as I try to overcome the fatigue factor.
We have to keep our equipment up to date because you are right if we are using outdated equipment, then what is the benefit of the instruction we are offering. We are trying to train individuals to be competitive in their chosen area, if we aren't doing that then we don't need to be in the business.
