Speak about somebody you like a lot. Say:how old he/she is

There is one persone I'd like to tell you some words about. This is my elder sister Vitalina. She's 25. I admire her and would like to resemble her.
   She's a very optimistic person: whatever  the situation is. Vitalina has a long blond hair and she toll and so beautyful.She always keeps smiling. Vitalina is also very helpful.  She is very persistent, enthusiastic and hardworking. At the same time, my sister is a wonderful wife and mother of two kids. I wish i could be the same person as my sister is.
