Idea book

I have a lot of trouble getting book ideas. I have bin on wattpad for maybe 4 to 3 months and not one idea came to me so this is the only one that came. You give me some ideas and ill put them down in to this book then ill see if I like any. If I do I'll follow you and use your idea. If I don't i will still follow you because you have me an idea but I will not use it for a book( well maybe ). So please do help me and to give me an idea go to my profile and ill tell you how.
