That's all true enough; I've had plenty of jobs given me I haven't really wanted to do and days when I was bored out of my skull, but I think generally you'll have an easier time at work if you're doing something you have a natural aptitude for.
I recently got away from the dictates of customers in the trade and am now painting only what I want to paint, although of course it's still going to have to be what others want to buy. Perhaps this won't last, but I'm already enjoying my 'work' far more now than at any time in the past 30+ years.
