You do have a choice: practice. Think of it this way.
If I were to ask you, assuming that you can't play the piano, to sit down at one and play Chopin's Nocturne in C# Minor; or to pick up a guitar and play the solo in Stairway to Heaven having never touched a guitar before, you'd think it unfair.
These people practised the sh*t out of their art-form to become as good as they are, and the same applies to anything you want to be good at. Athletes train at an insane level because if they don't, they'll under perform.
A lot of the top posts I've seen on steemit are from people who have written before, either on a blog or as a profession.
Don't be hard on yourself. Give yourself some time to learn the skill.
