Can you use は twice in a sentence?

Question

Can you say 'アンナさんの性格は明るくなくて、少しつめたいので、新しい友達ができるのは難しいです。’ or does it sound a little awkward? Can you use は twice here in a sentence? What I'm trying to say here is that because Anna does not have a bright personality & come across as a standoffish person, it's hard for her to make new friends. Thanks for your help!

Answer 1

Unlike が and を there is nothing wrong with は twice or even thrice. eg. (someone edit in a better one...)
