Look in the mirror
When inspiration is running dry, and you hit a wall in your writing, your pen is dry, or your keyboard is frozen – look in the mirror. What? – you must be thinking. Yes, look at your life, the situations, the people around you, the town where you live, the whole that is YOU. There is plenty of inspiration around you, and in you. Unless, you live in a dark cave with no entrance, and even then, that can make a great story. How can you see in there? How do you get out? What do you eat to survive? and so on – soon a story develops.
So, the next time that you are struggling with the paper and pen (or your fingers at the keyboard), get up and look in the mirror.
