I feel that I'm going to be a bad mother but I also want to be a mother?

One of my dreams in life is to be a Mom but recently I've been observing other parents and kids and been doubting my abilities to raise a child. I think I'm the type of Woman who loves babies and toddlers but once they start speaking and grow up I feel like I don't know what to do. I'm always very nurturing and affectionate towards babies and toddlers and when I spent a whole week with my friend's 9 month old baby I was super invested in taking care of the baby, entertaining her and feeding her and I think I'm very good at that but I feel that kids and teenagers intimidate me especially when they're very outspoken and start having opinions I don't know how to deal with that. Growing up I was a tough teenager and I think my parents weren't prepared at all to deal with that I'm terrified if my kids turn out as rebellious as me I wouldn't know what to do I don't want to be the annoying parent always annoyed at everything they do and say. Anyone feel the same?
