Finish my book which is 3/4 ready

I have written a book which is 3/4 finished it needs more short chapter research and more content but i just dont have the time to finish it and to find more compelling stories to write. I would need 10 more stories to be added and also probably take out a few that I have as they are boring. the genre of the book is about mind set and if someone tells you you cant do something and then people go and achieve it anyway. I added my own stories (ran the london marathon, had IVF alone and have beautiful twins now) but also loads of inspiring other peoples stories, some researched online , some celebrities, some historical characters and some personal stories of people that i interviewed. It's just not good enough yet it really needs someone to finish it.
