No matter how hard I try make my son more responsible, he only does it at the start and then slips back into his usual lack of concern and easy ways.

How old is your son?

Responsibility is learned over time. Some people come to it naturally, but some just have to grow into it. And focusing on it for the long term isn't easy, especially if you don't like to do something.
