Welcome to Psych Central. I read your post and can empathize with jack of all trades master of none.

What strikes me as a blatant mistake is to compromise your work by doing things other than work in work. This is grounds for dismissal where I work. Being without a job in this economy is not an easy thing to deal with.

I would say make or learn about electronic music on your time, but give the boss his 8 for 8. Eight hours of work for 8 hours of pay.

You could just be a searcher. Perhaps this book might inspire you on your non-working hours. CALLINGS by Gregg Levoy. It tells of people who meet obstacles and find new inner callings. It is not a book of answers as much as it is a book of questions.
