I think that sentence form works best because it forces you to actually decide and narrow your attention to an achievable number of topics and gives you a clear, unambiguous goal to pursue. The more clearly you can define what you want, the better your chances of getting it. (As an example and aside - look at the mission statements of large, powerful companies as opposed to failing companies - you will often see that the mission statements of the large, successful companies are a brief, direct sentence whereas the failing companies might have a paragraph or even several pages...a lack of focus as to the true goals of the company. People then become confused about what their ultimate goal is and become scattered).
