If you look at all the famous stories they usually follow the Hero's Journey. This tracks your character's experiences from beginning to end. This outline was created by Joseph Campbell and later reworked/explained by Christopher Vogler. Both these men had a big part in creating better stories & better writers.
You can fit Star Wars, Harry Potter, The Wizard of Oz, Iron Man all into the format of the Hero's Journey.
