Writing is like a sport - you only get better if you practice
If you write every day, you're going to write a lot of things that aren't terribly good, but you're going to have given things a chance to have their moments of sprouting.
The writer learns to write, in the last resort, only by writing. He must get words onto paper even if he is dissatisfied with them.
If you practice anything enough, you can be consistent.
As with all other aspects of the narrative art, you will improve with practice, but practice will never make you perfect. Why should it? What fun would that be?
