Thoughts about my dissertation topic

Hello everyone!!!
I'm completely lost in my own ideas about my dissertation topic. There are so many things that I'm interested in and that I'd like to write about. I can't put them together and make something similar to dissertation topic. Well, I'd like to write about sponsorships, mainly in sports or dance festivals. May be focus on innovations and new technologies in attracting sponsors. Or aims of sponsors and ways of returning invested money. I have found a lot of interesting articles about sponsorships in mega-sporting events. I would be grateful if anyone suggested some ideas!!!
