Yes, I think that it’s the way things are: you must work hard to obtain results.
This is true in a variety of situation. More or less, it’s true basically everywhere.
Take the case of art, for instance.
This is a field in which misunderstanding is quite common, on this topic. People are used to think that great artists are people who let flow art naturally from their hands. Naturally, i.e., without (too much) effort.
Problem is, things are different. Artists are ordinary people which a strong urge to make art: following this sort of calling they are simply determined to work hard till they obtain the desired results (avoiding the traps of perfectionism).
Of course, talent matter.
But, talent isn’t all. Work and regular practice is even more important.
I can speak only for myself, of corse. I cannot say how much talent I have in writing. But I can assure you that my best results have come in that cases where I convinced myself to spend a good amount of time on a given project. Making myself available also to write and re-write till I was not satisfied.
To listen to suggestions. Even to change the plot, in some crucial points.
I worked on each chapter of my novel Il ritorno (in italian) for a lot of time. Plenty of time, actually. One thing I can tell you, that all that works succeeded in improving considerably the manuscript.
First draft is always frightening, even if – it can contain some gems inside.
Working till the light of the gems comes out, it’s the hard part. But it’s necessary.
And, after all, it’s what each person who love writing, is willing to do. Because he know that he has no change, nothing different than take his art seriously.
And it pays. Always.
