There is no one point when one “becomes” a designer. There is always more to learn, and years from now, you’ll probably find something basic you never did. But there is certain skills that you really should have, terms you should know, tools you should be comfortable with, and concepts you should be familiar with. Here’s a list for you to reference as you go through your education – or educate yourself. All of these are best learned through actual design, so don’t wait to complete the checklist before you start designing. Design away, and don't be afraid to ask for help (especially from Google).
