Answer:
2. Type anything to get comfortable with the process.
Step-by-step explanation:
As a writer and poet myself, spending an entire day writing without taking breaks doesn't work and will only make you get burnout or writer's block.
Write while standing up to finish the assignment faster doesn't help either. Many writers have their favored positions (standing, laying down, sitting, etc), but no scientific studies have actually shown/proven that standing up will help you write better.
Refuse to write anything until you've finished the assignment is also not the way to go. This will only create more procrastination and lack of motivation. You'll actually get worse at writing. Writing is like a muscle, the more you practice and write, the better it will be.
Type anything to get comfortable with the process is the right answer and is a great way to get comfortable with writing and get out of writer's block. Write anything you want to write first. By this, you'll find your motivation and familiarity with words go up and you'll find it easier to write. Write, write, and write!
Have a lovely rest of your day! :)
