Analysis- Will I vs. I will

 The difference between "will I" and "I will" is the fact that one is a question while the other is a command.  We would normally expect people who say "I will" to themselves to have more success; it shows more determination and confidence than saying "will I".  However, a startling study shows that those who say "will I" to themselves will actually obtain more success.

 I personally think the reason is because the statement "I will" rouses a sense of anxiety when someone says it.  It carries a feeling of a final decision and pressure.  "Will I", on the other hand, has a wavering tone that one uses in the middle of decision making.  Thus, one will have the tendency to explore the pros and cons before making the decision. Once the objective of the decision is clear, a strong foundation is formed and the person will complete the task with less pressure and more success than the one who said "I will".
