'About me' portion in portfolio

Hiii!

I hope someone can help me out! I'm new to this world, I'm creating my portfolio right now and I had a question about the 'about me' section. Firstly, I don't have any previous work, I don't post often on my social media accounts, so I don't know if I should still link my instagram or not. Also, do I create other accounts with 'ugc' in the title and link that?
Second question, in the 'about me' section should I just do a little summary about what I studied, that I'm new to this, how old I am, where I'm from and etc or do I have to say "im a ugc creator focused on x,y and z" even though I haven't gotten any deals or anything. Also, do I put rates at the end of my portfolio even though I have no idea what to put and what that means?

Thank you, any help is welcomed!! I'm hoping to start filming with products I have at home tomorrow, so I'm excited!
