Write the truest thing you know. If it is the truest sentence you can write, you will not need descriptive adjectives.
Write until you feel done for the day but always leave a next step, a next story for the following day. Always leave something get up to write for.
When you are finished writing for the day, leave the writing alone. Go for a walk, a nice dinner, read a good book, anything that keeps the story out of your mind. Allow your subconscious to work on the story.
