Passion Is a Side Effect of Mastery
The myth of the virtuoso is also a problem," Newport says. "In the majority of cases, people didn't think of someone who became a virtuoso as having unusual talent when they were very young."
Instead, most highly skilled people were exposed to something in a way that made it interesting. Take music: Something (a song, an instrument, a teacher, etc.) initially inspired them. They started learning and then benefited from what Newport describes as a feedback effect.
Someone once said that a writing career was like always having homework.
So never concern yourself with your writing "talent." Practice writing every day instead.
