Trying to treat My Girlfriend the way she should be treated?

Its my girlfriends birthday on friday and i want to9 do the best i can for her. She is my best friend and my everything. We do everything together and i need to be the best i can for her. This includes making her bday as good as possibleI dont have that much money as i am only 17 but i am planning on giving her roses and a card that i will make by myself. I have been working all week for my dad just to save enough money to giver her something. I am also giving her a book i have made for her which took me a long time. Its a book about us. half of it is about my past and some of the mistakes ive made and is quite Insightful and the other half is about how she makes me feel and our fondest moments together. I am staying at her house that night and am going to give her a mage and then suprise her with a gift of her favourite perfume which is vanilla. But in order to get the purfume i have to sell one of my guitars to get enough moeny so ive done that. Being a boyfriend is hard and living up to my expectations in myself is too. I want to know your opinions especially girls on anything else i could do?
