Write about someone finding a key. Do they know what it belongs to? Maybe it opens the neighbor’s car, or an old box, or even police handcuffs. Think of a creative scenario. What ends up happening to the protagonist, and the key itself?
Have you ever observed nature closely? Have you ever noticed how a seed fights the the earth to emerge into a victorious plant? Have you observed how a bird, with precision and hard work, finally manages to build its nest? Nature does not give up. Why should you? Just don't give up trying to do what you really want to do. Where there is love and inspiration, I don't think you can go wrong.
