1. Look for the inspiration!
If you haven't even started to compose your own musical piece and already feel like all the inspiration has abandoned you at the moment your hand picks up a pencil, don't give up! Look around you! Do you see something interesting? There should be some objects around you that make particular sounds or rhythms. You can also read a story and try to portray it in music. There are so many options. Open your eyes and ears and be brave enough to give your music a chance to be written!
