Aren't teenagers always answering this question or some type of similar variation? Well I have a few things in mind for myself.
If I didn't have to be realistic, I would say model. I would loooove to be a model someday even if it wasn't my entire career. However I have absolutely no way into that field considering the only modeling I have ever done is for Vera Bradley's website.
Another one of my 'fantasy jobs' is an interior or fashion designer. Again, I have little to no experience in this field and choosing this as a career isn't logical or realistic.
Being realistic now, I want to be a teacher. I would love working with younger children or high schoolers. I think that helping kids start their schooling or end it would be great. My personality would be perfect for either age, or at least I think it would (:
Also, the job I have wanted since 3rd grade was to become an architect. My aunt is an architect and I think that is where I must have gotten the idea. If you were to go through my closet you would find various floor plans and multiple drawings of the layout of our actual house draw to scale.
