Looking for inspiration is a very necessary thing to do. Because every professional artist would need inspiration to be able to pour it in every scratch of his work.
If someone wants to draw a sketch, but he has no inspiration then the result will not be maximized and the created image has no meaningful meaning.
If you still have no inspiration, then try to get out of your house. You can take a walk to see the beautiful scenery around you. Can be a mountain, beach, forest, rice fields, and historical places that will cultivate your inspiration
