Hello, I totally relate with your project because I'm a young lady of 28 and I have two younger sisters, 23 and 20 and they look up to me. I also have a cousin that's 22 now and in the university, she sees me as her big aunt she can run to anytime.
They are open with me and they tell me everything going on with them, on which I advise them all the time. The youngest is 20 and I am proud to say she calls me her role model.
My point here is that I am good with people, generally I'm the kind of person people come to for advise, giving my lifestyle and they try to emulate me.
I can coach your daughter, and tell her what she needs to hear and understand about life. I've come to understand that making younger ones open up to you, you have to be their friend.
I can be a friend and a big sister to her and coach her properly.
I can tell you more via chat.
Thanks
