Question

Hi, I am tasked with writing a concept paper, but i need ideas. The topic is anything I want, which sounds awesome but I just need the right idea to write a really great paper, my first idea was the fall of oil prices and it's effect on major economies, but than I narrowed down the concept and completely took a turn for subjects and decided to use the concept of Ambition and write a 4-5 page paper on that using sources.. any helpful hint or suggestions would be great, the only reason its taken me this long to write this is because I am really trying to nail this one. Thankyou :)
