I have heard them all...the reasons so many solo artists and band members give for not learning about the business they are in...the Music Business:
The Top 3 Reasons are:
1.They can't afford any courses, classes, books, or workshops.(in truth no musician can afford NOT to educate themselves about this crazy, ever-changing business)
2.They believe that if they know the right people in the music business, they won't have to bother with learning how their industry operates, their contacts will take care of them.(and will they ever!!)
3. Leaning about the music business will take too much time away from creating their music.(yes, and more likely unscrupulous businessmen and women will exploit that very creativity they are so enamored with.)
Now, I may not have heard all the reasons for being ignorant of the inner workings of this business.
I'm sure you have your own reasons for avoiding this issue, but all I am asking you to do is examine those reasons. Ask questions about how things work!
That would at least be a start!
To paraphrase a well-known saying: "The career you save may be your own!"
