When faced with a chance to EITHER make more money than you ever have in your life... or be involved in a situation that is absolutely perfect for your professional 'art' but not that stellar in the effort/money ratio....
it depends.
does the job with more money allow you time to enjoy it?
is your professional 'art' something that you could do for fun on the side/weekends?
is the lower paying job something that you KNOW you'd enjoy, or might it become a chore eventually?
would it mean that you struggle to make ends meet?
I somewhat took that challenge on with my current job and love was the answer. I work long hours in a very stressful, demanding environment - if I didn't love working I would be a wreck.
