new to freelance work

[#1]

Good day,

I am new to freelance work. I thought I'd ask if it's it alright/wise to mention this to proposals I am to submit? Thank you.

Two key things to consider:

One: Any client whose job you apply to can click on your name and see your profile page. They will see that you have no Upwork experience.

Two: How would it benefit you to mention that you have no freelancing experience? That doesn't sound very wise to me. If a freelancer told me that I would know that she doesn't understand how Upwork works, and I would also know that she doesn't have confidence in her ability to work on my project.
