Wow, music, art, dev, you did quite a lot. Nice. I plan to try music (drums to be precise), but time..

Anyway, this has been a problem since forever. That's why all kinds of occupations like singer managers, sales, marketing etc. exist. It's all perfectly normal.

For you, it would be good to find someone compatible, someone to take care of presenting your work to the public while you can focus on creating.
