DGXL,
I too have noticed the decline of intrest in our field. It seems it is hard to get kids off the couch and to drop the gameboy long enough to pull up thier pants and be motivated towards working at anything. It seems they think a good job is making lots of money without working for it. Good work ethics are something our fathers and grandfathers had, but somewhere we've lost it. I didn't come from a family with money, so I feel what I have worked for, I have earned. It makes you take care those things because they were not so easy to come by. I think education has gone down the same paths. People want degrees and make big money, but want it now, before they have earned it. Education is a great resource, but we've made it too easy for our kids. We want our kids to do well in the world, but they have a hard time appreciating it because we've worked hard to make it easy for them.
I agree with Lawrence, Those guys only came back because they had put forth the effort and was proud of what they had accomplished in completing your class,
Keep your chin up!
