As I was reading David Suchet’s memoirs of his awesome Poirot run, I ran across this awesome Agatha Christie quote, echoing Stephen Pressfield (or actually presaging him …) on turning pro and doing the work.

That was the moment when I changed from an amateur to a professional.
I assumed the burden of a profession, which is to write even when you don’t want to, don’t much like what you are writing, and aren’t writing particularly well.

All that matters, is persistence, slowly inching your way towards your goal; doing the work even when it’s hard and you don’t want to.
