Do you make your sim self?

I've tried several times, and only so many because I can never get it accurate enough. It's a fun challenge, but also frustrating. I feel like they look like alternate dimension versions of myself, where they look like me mostly but something is just kind of off. I never play as my Sim self though. I make her purely for the challenge of making a Sim look like a real life person. Part of the reason I don't play is because I feel like I need more space for traits. Real people have so many traits that make them up, it's so hard to just pick three! And none of the aspirations really suit me (if I even knew what I wanted irl, lol).
