@marlenec Your son's concept that he grew up with every advantage doesn't always translate into putting everything into successful practice. Little victories each day can be built upon, creating a positive foundation. I sincerely hope that he will continue to look for the ways that will work for him, and consistently take pride when he has managed a good day. It takes a lot of hard work on his part, and it sounds like you understand all too well, how discouraging setbacks can be. The phrase "never give up" comes to mind.
