Because we all have to start somewhere.
Before making hoards of girls pass out by just being there and being incredibly popular in the Philippines (among other countries), international music-sensation, Justin Bieber, started out doing this:
Singing to his favorite RnB tracks in the living room and posting the vids on Youtube.
Look at where it's brought him.
The internet changes lives, really; So keep doing your thing online.
Who knows, you could be the next Justin Bieber (or Dan Johnson Externon, for that matter). :D
