I just revisited a chap I found via youtube a couple of years ago. He was being slanged out for his cover of a song I really like. He had some issues but in spite of what people were saying I thought he had huge potential. So I took the time to PM him and offer support and a few musical pointers, chat to him about stuff in general. I felt a bit goofy, but figure if you can help then you should, right?
Anyway, it seems like he's gone on to do more singing, and to improve, and also to go on to help other people including taking time to go teach sick kids in hospital. I'm not going to take much credit, but I'm sure if you help other people they sometimes in turn help other people. I just thought it was kind of cool.
