I’m stupid did I mess up?

I never go up to girls ever, because I’m focused on myself and just working, but the other day across from where I work the restaurant I saw the most prettiest girl ever! I looked at her, she caught me smiling at her as she was setting up the tables! I get to my job which is across hers, when I notice her again staring in my direction, my coworkers say dude she’s into you go up to her ask her out, so I did! I went up introduced myself, told her I think she was very pretty and I’d love to take her out, I asked did she have a boyfriend she said she didn’t and said sure to me asking her out. She was smiling and kinda shy, so I face her my number and she said she’d text me and it’s been 4 days and I still haven’t heard from her. Everyone tells me that she’s probably busy or not know what to text or say or that she wants me to make the first move. Like she gave no impression she was just “being nice” or not interested. So should I go up to her again if I see her at the job she’s at when I’m at work?
