Wow! Such a pretty sound you played, I think it really portray calmness as one can draw lot of inspiration once on this kind of harmony. Moreover Mr. Daniel's lecture can also help someone in minimizing stress given the lot of problems and bugs our human minds cannot control at an instant. Well, I trust it'll help your son anyways, if he's ready to heed to the words of Mr. Daniel since it's not all about the volume of idea and advice that's important in anything but the readiness of the listener to heed to instructions that matters in everything.
