not too creative or imagintive?

i realized every time i write a short story and i have to create a main character, the character always has the same traits and problems as i do. is this just me not being creative with my writing skills or me not being imaginative and going out of my box? i don't know these answers but maybe it give me self realization and self learning. i have no idea. maybe it's normal. oh well. i just felt like i needed to share this.
