Here’s a writing tip that will make your life easier.
Outline first. Spend some time figuring out the main points you would cover. Just broad ideas are enough.
Take a break. Live your day. Sleep.
Wake up. Now, expand the ideas.
Don’t try to outline and write on the same day. Give your brain some space and time to breathe.
Have a session for outlining. Have a session for writing.
But do not combine the two.
