Inspiration can come from anywhere. Whether you're observing people or from things you see in everyday life, and the most obvious is from photos from other photographers. But, if you want to be a little more creative, you can take ideas from other forms of media. Like, music or TV. Maybe even other things like sports. Two football players colliding can be translated to taking a photo of two hard shell eggs colliding. Use the music you listen to. Even bad music.Anything. Just think: "How can i make a photoshoot out of this?"
Keep your mind and your senses open.
