Sophisticated writers take time to brainstorm and organize their ideas in the PREWRITING STAGE of writing. Then, they DRAFT multiple versions of their writing piece, chiseling away at their work like a sculptor does a hunk of marble. And then they REVISE and EDIT their work, further perfecting their writing pieces, and making sure they are unique, on-topic, and compelling. And then, when all of this hard work is complete, it is time to publish and present their work.
No writer writes to "no one." Not even the diarist. Even she is writing to someone very close to her...herself.
Respect and communicate well with your audience. And do so by taking the time to create solid written prodcuts...one step at a time.
