keep it real.
Don't front and try to be what your not.
Just enjoy your work or hobby where ever you are in your music experience.
Always try to stay fresh because somethings can get old.
And if something is not turning out right then put it down and come back to it.
As for promotion.
The internet is key.
There are plenty of sites that allow you to share your music to the world.
YouTube and or Sound-cloud for sure.
even for Facebook if you are just trying to share it to some friends.
