Close your eyes and picture a typical spring day where you live. What is the weather like? How do you feel? What things do you see, feel, touch? What foods do you typically eat? Where do you go only in the spring?
Write this down.
Move on to summer. What things do you only do in the summer? Record how you feel, think, what you see, taste, touch.
Do the same for autumn and winter.
Looking over your list, do you see a pattern?
Your task is to create a comparable list for your character. It makes no difference the genre of your writing. What matters is that your listings be accurate for the place and time of your work.
Once the list is complete, choose the season you feel most comfortable writing about. Place your character in the story with at least one other person. Turn on the action. Make sure to include those details that impact your character the most.
When you are finished, reread looking for sensory details. Make sure that you did not list them, but rather revealed them slowly, one at a time.
Have fun with this one.
