Here's why:
* Focus on ideas first: The first draft is about getting your thoughts and ideas down on paper. You're brainstorming, developing your story, and exploring different avenues. Focusing on perfect grammar and spelling can actually hinder this process.
* Easier to edit later: It's much easier to edit for errors once you have a complete draft. You can see the flow of your writing, identify awkward phrasing, and refine your sentences more effectively when you're not preoccupied with every single word.
* Avoid perfection paralysis: Aiming for perfect grammar and spelling from the start can lead to writer's block. You might get bogged down trying to find the "right" word or stressing over every comma. This can prevent you from completing the draft altogether.
However, that doesn't mean they're completely irrelevant:
* Basic readability: While perfect spelling isn't necessary, basic readability is important. Ensure your sentences are grammatically sound enough to be understood, and that your spelling is clear enough to be read.
* Focus on the flow: Pay attention to sentence structure and word choice that impacts the flow and rhythm of your writing. These elements are important even in a first draft.
In short: Focus on getting your ideas down in the first draft. You can refine your writing and edit for spelling, grammar, and word choice in later drafts.
