You might like this book. Can't remember where I heard about it. Might have been on this forum. "How To Become A Famous Artist and Still Paint Pictures". You can get the PDF version free at the authors web site:

He covers the points Gordon and I have made in the past about how a passion (painting in this case) becomes a burden after it becomes your job.
I enjoyed the book overall.
Worth a look.
