My son is 35 now, didn't have any issues with him with these rules. We did tell him in College not to get a job, that we would cover all his expenses. His Junior year, under pressure from his girlfriend, he got a job. His grades fell forcing him to stay in College an additional year at a cost of about $50,000 in tuition and room and board. How much did he make in his job? $7,000! But it was a life lesson. And his girlfriend has been his wife for 6 years now, so it worked itself out, just with a price.
My daughter is 31 now, the no concerts on school nights were an issue for her at the time. She recently brought it up and said that in hindsight half of her wonders why we had the rule, and the other half of her wonders why she wanted to go to those concerts. She wanted tattoos and piercings, but two friends got them and one had an allergic reaction to the ink, and the other got an infection and she lost interest in that. She did get her ears pierced at 18. I think the holes have closed because she never wears earrings.
