The first song you write and release will probably be ignored.
The tenth one maybe not.
The twentieth will probably do something commercially.
The thirtieth, will probably be ignored.
What is clear is that each song, creates more demand for other songs. Each song released gives you the power to release better songs. And better songs create more demand for other songs.
So in order to survive creating, you need to do something creative.
And then don’t stop.
