MAC is VERY overwhelming for your first time around. I've been using MAC for over 10 years now, I'm 31 now, so at 21 I was really intimated. To this day when I go in there I feel ugly. I don't know if it's the high powered lighting, or everyone made-up flawlessly that makes me feel so self conscious about myself, when in reality I'm not at all. I think it is very important to find a SA that can relate to you. I was so discouraged my first couple times, I came home called and spoke to a manager at the MAC store, and explained my situtaion. Then she hooked me up with a good SA and I can in the next day (which was a slow day), and everything was good to go. Here's my advice, call the MAC store, have the manager or asst manager hook u up with a good SA and schedule your makeover before you go in (on a weekday where its slow, so your not as pressured and they have time to pay attention). They can explain products, etc. I have a PRO store in my area which I've been a member for years and have taken the makeup classes. Believe me please consult with a SA before purchasing anything.
