How to get my pup to be more interested on walks?

I have a 9 month old sheltie who is absolutely great. Leash training her has been seriously so easy and such a breeze. She has basically never gone through a phase of wanting to pull or acting crazy and I think it’s because I made a strong effort to be the absolute most interesting thing to her. Well now she only wants to be by my side, she’s almost always engaged with me and uninterested in anything else. She will very occasionally stop to sniff something briefly but otherwise she is completely uninterested in exploring. How should I get her to explore more? I have a 30ft leash and open field but she just simply does not want to go explore. I feel worried she does not enjoy going on walks and would like to make them more fun and exciting for her.
