We will begin talking about your learning capacity. Employers often take into consideration the passion behind the designer. If the potential designer does not posses the exact skills needed it will be easy for the employer to understand that you can learn the skill in a short amount of time. Most often it's a skill that you have been very interested in but have not tasted yet. Passion is the most important factor in becoming a great designer.
Creativity goes right along with passion.
You can tell if you're passionate about your field if you sometimes go into a creative black out. Your body won't let this happen unless the passion is there. Your brain shuts off pre-conceived barriers and outside interference, thus letting your creativity do the work. This happens while both learning software and creating art. It will be easier for you to understand why and how the piece was created.
