I think it's a terrible thing to write and not enjoy it. It's a sad thing. But of course a lot of people do work because they need to eat. And we all need to eat but that's not the only reason to work. You couldn't have paid me not to write.
I find writing very difficult. It's hard and it hurts sometimes and it's scary because of the fear of failure and the very unpleasant feeling that you may have reached the limit of your abilities.
